Which would have greater species diversity a small forest or a cornfield?
A small forest would have greater species diversity than a cornfield because species diversity tends to increase with diversity of habitats. A field consisting of just corn is a fairly uniform habitat and cannot support as much life.
What is diversity in ecology?
The variety of life across all levels of ecological organization. Species diversity The number or variety of species in a particular region Genetic Diversity The differences in DNA among individuals within species and
What is the importance of genetic diversity and biodiversity?
Genetic ....... is important for agriculture because wild plant stains may have useful traits that can be passed on to their crop plant relatives. diversity Biodiversity is important to the field of ...........because many treatments, including some for cancer and heart disease, come from plant compounds. medicine

Which type of habitat would have greater species diversity a small forest or large field of corn?
A small forest would have greater species diversity than a cornfield because species diversity tends to increase with diversity of habitats. A field consisting of just corn is a fairly uniform habitat and cannot support as much life.
What is a habitat with high biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
Which category has the highest diversity of species?
Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.
Which can be best considered to have high species diversity?
The species diversity varies in a different geographical location with tropics having highest and declines as we move towards poles. The most species-rich environments are tropical rainforests, coral reefs and ocean bottom zone.
Why is species diversity greater in tropical regions?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
What is high diversity?
Biodiversity refers to the number of biological species that exist in a given region. High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few.
Why are some habitats more diverse than others?
The size of a habitat is another factor in the great diversity of the rainforest. Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.
Where is species richness the highest?
tropical latitudesSpecies richness is generally highest in tropical latitudes, and then decreases to the north and south, with zero species in the Arctic regions. Global species richness as calculated for mammal species.
What determines species diversity?
Species diversity is determined not only by the number of species within a biological community—i.e., species richness—but also by the relative abundance of individuals in that community.
What is species diversity example?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the naked eye.
Why would a small forest have greater species diversity than a cornfield?
A small forest would have greater species diversity than a cornfield because species diversity tends to increase with diversity of habitats. A field consisting of just corn is a fairly uniform habitat and cannot support as much life.
What is the study of how organisms interact with each other and their environment?
the differences in DNA among individuals within species and populations. Ecosystem diversity. the number and variety of ecosystems. Ecology. the study of how organisms interact with each other and their environment. Species. a group of individuals that interbreed and produce fertile offspring.
What is the greatest cause of biodiversity loss?
Habitat destruction or change can limit the number of species a habitat will support. This is the greatest cause of biodiversity loss! Describe overharvesting. Species may become endangered or even extinct if they are trapped, hunted, or otherwise harvested faster than the species can reproduce and grow.
What is an endangered species?
Endangered species. a species that has a high risk of extinction. Threatened species. a species that is likely to become endangered soon throughout all or part of its range. Habitat fragmentation. the process by which the land that is suitable for wildlife becomes separated into smaller patches that are not connected.
What happens when a species dies?
Extinction occurs when the last member of a species dies. Extirpation, on the other hand, occurs when a particular species disappears from a given area only, not globally. Describe habitat alteration. Habitat destruction or change can limit the number of species a habitat will support.
