For populations to survive, their life needs must be met. This includes finding food, defending themselves, and reproducing (3.4 b).
No resources have been tagged as aligned with this standard.
All the organisms of the same species that live in the same place at the same time are a population (4.3 a).
The populations of species that live in the same place at the same time together make up a community (4.3 a).
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).
If animals’ needs are not met, they move to an area that does meet their life needs. If they cannot move, they will not survive. If a plant’s needs are not met it will not survive (K.7 a).
Many animals benefit from plants. Plants provide food, shelter, and oxygen. These are required to meet basic life needs (2.8 b).
