Members of a population interact with other populations in a community. They compete to obtain resources, mates, and territory, and they cooperate to meet basic needs (4.3 c).
No resources have been tagged as aligned with this standard.
A population is a group of organisms of the same kind that live in the same place (3.4 a).
Organisms depend on each other and on the nonliving components in their environment. They often compete for limited resources (3.5 b).
For populations to survive, their life needs must be met. This includes finding food, defending themselves, and reproducing (3.4 b).
An ecosystem supports a diversity of organisms that interact with each other and their nonliving environment (3.5 a, b).
Nonliving components of an environment include sunlight, water, nutrients, soil, and air (3.5 b).
