living organisms modify their environment a little at a time

animals move out of the ecosystem until succession is complete

parts of communities split off to form new communities

an ecosystem reaches a final, unchanging stage

20.

1 point

The repeated movement of water between Earth's surface and the atmosphere is called

precipitation

hosts

prey

mutualists

predators

22.

1 point

A wetland that contains a mixture of fresh water and salt water is called

a stream

an estuary

a river

a pond

23.

1 point

occupy different niches within the tree

have different habitats within the tree

can find different temperatures within the tree

don't eat food from the tree

24.

1 point

A symbiotic relationship in which both species benefit is

predation

commensalism

mutualism

parasitism

25.

1 point

the seasons

ocean upwelling

26.

1 point

The nutrient availability of aquatic ecosystems is the

number of other organisms present in the water

amount of rainfall the water receives

amount of nitrogen, oxygen, and other elements dissolved in the water

number of different animal species living in the water

27.
