Resources in Ecosystems

What is a population in ecological terms?

• A group of different species living in the same area

• All the ecosystems found within a specific area

• A group of individuals of the same species living in the same area

• The maximum number of individuals an environment can support

How does a species differ from a community?

• A species is a single organism, while a community is a group of organisms.

• A species includes all the ecosystems where it lives, while a community does not.

• A species is a group of individuals that can interbreed, while a community consists of different species.

• A species can live without a community, but a community cannot exist without species.

Why is the concept of carrying capacity important for understanding ecosystems?

• It helps in identifying the most dominant species in an ecosystem.

• It determines the biodiversity of an ecosystem.

• It indicates the maximum number of individuals an ecosystem can support without degradation.

• It shows the total number of species in an ecosystem.

How can the carrying capacity of an ecosystem be altered?

• By introducing new species into the ecosystem

• By removing all the predators from the ecosystem

• By changing the availability of limiting resources

• By increasing the biodiversity of the ecosystem
