Question

1. which best explains biodiversity? a. the population of a species in an ecosystem b. the variety of species in an ecosystem. c. the study of life d. the different number of biomes on earth. 2. which is not one of the benefits of biodiversity? a. economic value b. uniform genetics in a species c. survival of species in the ecosystem d. cultural value 3. which is an example of genetic biodiversity? a. different skin color within a species b. different types of species in an ecosystem c.every organism has the same genetic sequence d. all populations look identical within a species 4. which ecosystem has the greatest amount of biodiversity? a. polar regions b. deciduous forests c. tundra d. tropical rainforests

Explanation:

1. Biodiversity refers to the variety of life in a particular habitat or ecosystem, which is best described by the variety of species in an ecosystem.
2. Biodiversity provides economic value (e.g., through natural resources), helps in species - survival in the ecosystem, and has cultural value. Uniform genetics in a species is not a benefit as it reduces adaptability.
3. Genetic biodiversity is shown by variations within a species, such as different skin colors within a species.
4. Tropical rainforests have the greatest amount of biodiversity due to their warm and humid climate and high levels of primary productivity.

Answer:

1. B. The variety of species in an ecosystem.
2. B. Uniform genetics in a species
3. A. Different skin color within a species
4. D. Tropical rainforests
