• where the population is growing exponentially

• where the population is level

• where the population drops off

• where the population is highest

what are limiting factors?

• all of the non living things that impact population growth

• density dependent factors

• a measure of biodiversity

• the living and non-living factors that control population growth

An invasive species has been introduced to a pond, using up many resources and resulting in the decline of several pond species. The same invasive species is introduced into the ocean. What is the most likely impact on ocean biodiversity?

• very little impact, the ocean is large and has high biodiversity

• a big impact, the ocean has more species that can be affected

• very little impact, the ocean is large and has low biodiversity

• a big impact, the ocean is small and not that many species live there
