A

D) Community

35
Q

How is a population different from a community?

A

A population is made up of all members of the same species living in the same area, while a community is made up of all populations living in the same area

36
Q

What’s the difference between a primary consumer and secondary consumer?

A

Primary Consumers eat producers, Secondary Consumers eat Primary Consumers

37
Q

What biotic factors might the predators compete for?

A

Primary & Secondary Consumers

38
Q

What abiotic factors might the predators compete for?

A

Water

39
Q

What might happen to the level of competition if the level of resources decreased?

A

It will increase because resources are hard to get

40
Q

What might happen to the predators if this change in resources occurred?

A

Most likely die because resources become extinct
