be a limiting factor

density dependent

Front

The highest population an environment can support is called

Back

carrying capacity

Front

Imagine a sea otter moves to an ocean bay area and eats crabs. What would happen to the ecosystem?

Back

The sea duck population will decrease (go down)

Front

What would most likely happen to the producers if a new predator was introduced to the ecosystem?

Back

The population of producers would increase because the predators would eat herbivores as prey, so there wouldn't be as many to eat the trees, shrubs, and grass

Front

What is happening to the birth rate vs death rate for the population at letter A?

Back

birth rate is more than the death rate

Front

Why does the predator population lag behind the prey population?

Back

Increase in predators leads to decrease in prey
