What is life cycle answer?
A life cycle is a series of stages a living thing goes through during its life. All plants and animals go through life cycles. It is helpful to use diagrams to show the stages, which often include starting as a seed, egg, or live birth, then growing up and reproducing.
What is the role of salmon in the life cycle?
In the wild, salmon is hatched in gravelly stream beds that provide protection from predators and abundant supplies of oxygen to the eggs.
How does the hydrological cycle work?
The hydrological cycle is schematically shown in Figure 1. Atmospheric water vapor condenses and precipitates as rain or snow. A small portion of this is intercepted by vegetation canopies, with the rest reaching the ground. A portion of this water flows over land as surface water toward the ocean or inland depressions, to be intercepted along the way by ponds, lakes, and wetlands. Another portion infiltrates to recharge the soil zone between the land surface and the water table, and the groundwater reservoir below the latter. Pulled by gravity, groundwater can move down to great depths. However, because of the presence of low permeability earth layers, the downward movement is resisted, and water is deflected up toward the land surface to be discharged in streams, lakes, ponds, and wetlands. Water escaping the influence of resistive layers and moving to greater depths encounters geothermal heat. Geothermal heating too has the effect of countering downward movement and impelling groundwater toward the land surface. At the land surface, surface water and discharging groundwater are subject to evaporation by solar radiation and to transpiration by plants as they consume water for photosynthesis. Collectively referred to as evapotranspiration, this transfer of water back to the atmosphere completes the hydrological cycle.
What is the spore of anthrax?
Anthrax is an infectious disease caused by ingestion of spores of a bacterium that multiplies upon inoculation or ingestion and secretes lethal toxins. A spore is a refractile or stainable structure of a microorganism formed as a hypobiotic stage in the organism's life cycle that allows survival in environmental extremes. The vegetative form is a structure of a microorganism that develops when environmental conditions allow asexual reproduction or multiplication.
What are the adaptations of temporary waters?
Inhabitants of temporary waters are distinguished by their ability to survive periodic drying. Adaptations include diapause, quiescence, and active avoidance. Rapid responses to flooding, fast growth, and flexibility in initiating the drying response maximize organisms’ habitat use.
What is symbiosis in biology?
Scott (1969) arrived at a definition of symbiosis as a “state of equilibrated physiological interdependence of two or more organisms involving no permanent stimulation of defensive reaction mechanisms.” This is a synthesis of six criteria, the possession of any four of which he considers adequate to constitute a symbiotic association. These criteria are that the association should (a) be a permanent feature of the organisms’ life cycles; (b) involve physical contact between the participants; (c) involve unilateral or bilateral movement of metabolites; (d) ameliorate environmental status, thus giving rise to an extension of ecological range; (e) give rise to morphogenetic effects; and (f) provide opportunity for the production of metabolites not formed by either of the organisms separately.
What is Darwin's idea?
His idea was that the environment was not constant and thus environmental variation was a challenge organisms must adapt to. Selection in variable environments has been a major topic of study by evolutionary ecologists.
How does water break down rocks?
On the Earth's surface, water breaks down rocks physically and chemically through weathering, aided by solar energy and by actions of microbes, plants, and animals. The products of weathering are transported as sediments (bedloads and suspended loads) and dissolved chemicals. In addition, water also transports leaf litter and other decaying vegetation and animal matter. The sediments and organic matter together contribute to the cycling of life-sustaining nutrients. The habitats of flora and fauna along the course of a river depend, in very complex ways, on the texture of sediments as well as on their chemical makeup. A glimpse into the intricate influence of physical nature of sediments and the aquatic chemical environment on an organism's life cycle is provided by salmon, an anadromous fish. In the wild, salmon is hatched in gravelly stream beds that provide protection from predators and abundant supplies of oxygen to the eggs. Once hatched, the young fingerlings must have narrowly constrained aquatic chemical and thermal environment to survive as they migrate from a freshwater environment to a marine environment where they will spend their adult life.
What is the life cycle of an organism?
A life cycle is defined as the developmental stages that take place during the lifetime of an organism. In general, plants and animals go through three basic stages in their life cycle, starting as a fertilized egg or seed, developing into an immature juvenile, and finally transforming into an adult.
What is the simple definition of life cycle?
A life cycle is a sequence of events that establishes a new product and follows its growth into a mature product and ultimately to critical mass and decay. The most common stages of a product’s life cycle are product development, market launch, growth, maturity, and decline/stability.
What is a sample life cycle?
The definition of a life cycle is the series of changes that a living being undergoes during its lifetime. An example of a life cycle is a caterpillar turning into a butterfly. A progression through a series of different stages of development.
Why do organisms have life cycles?
individual organisms die, new ones replace them, which ensures the survival of the species. During its life cycle, an organism undergoes physical changes that allow it to mature and produce new organisms. Since these changes are common within a species, they can be grouped into developmental stages.
What are the stages of the life cycle?
The major stages of the human life cycle include pregnancy, childhood, infancy, childhood, puberty, adolescence, adulthood, middle age, and old age. Good nutrition and exercise ensure health and well-being at every stage of the human life cycle.

It is helpful to use diagrams to represent the stages, which often consist of starting as a seed, egg, or live birth, then growing and reproducing. Life cycles repeat over and over again.
What is a Life Cycle?
A life cycle is a series of changes that an organism will go through throughout its life, marked by significant stages starting with fertilization and ending with death. The cycle of life is unique to all organisms, and overall stages can change based on the species.
Life Cycle Examples: Life Cycle of Organisms
The life cycle of organisms is vast and varies drastically based on the organism. We will look at many different life cycle examples, including: mammals, insects, fish, frogs, birds, and flowering plants.
Animal Life Cycles
Select an animal that you are interested in researching and learning more about. Once you have selected an animal, research the life cycle of this particular animal and provide a brief written description of each stage. Use the following questions as a guide.
What is the life cycle of an organism?
Explanation: The life cycle of plant or animal (humans included) is the series of changes that the organism undergoes in its life. It starts at reproduction and moves through the different stages of life until it ends and begins over with the offspring.
What is an organism?
Explanation: The term organism refers to an individual plant or animal. An organism is a living thing. An organism can be as simple as a single-celled life form or as complex as a human. Each organism does have a unique life cycle or stages that it travels through from birth to death. Report an Error.
How does a frog start?
A frog starts as an egg and then morphs directly into an adult form. A frog starts with a tail, then grows wings, and finally, the tail shrinks until it is gone. A frog starts with a tail, then grows legs, and finally, the tail shrinks until it is gone. Correct answer:
How long does a caterpillar pupa last?
The caterpillar forms itself into a pupa or chrysalis, and it remains inside as it transforms into a butterfly. The pupa stage may last a few weeks to several months, depending on the species. The case around the pupa hardens to protect the caterpillar as it grows into the butterfly.
What is the butterfly's life cycle?
The butterfly begins life as an egg. Correct answer: The butterfly undergoes a metamorphosis. Explanation: A unique characteristic of the butterfly is that it undergoes a metamorphosis. The butterfly begins as an egg, then a larva (a caterpillar), a pupa in the cocoon, and finally will emerge as a butterfly.
What are the similarities and differences between ducks and humans?
Both humans and ducks are born, go through a juvenile stage, move into adulthood, and then have offspring of their own.
What is the characteristic of a frog's life cycle?
Explanation: A unique characteristic of the frog's life cycle is its loss of tail and the growth of legs! A tadpole has a tail, and slowly legs grow (two at a time) as the tail shrinks.
