LIFE SCIENCE

Detailed explanation-1: -Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors. This is the hierarchy of ecology.

Detailed explanation-2: -An organism is a single living thing, a population is all of the organisms of the same species in the same place at the same time, a community is all populations in the same place at the same time (all living things), and an ecosystem is the reactions between living and nonliving components in a given area.

Detailed explanation-3: -Community-A community is made up of the living components of the ecosystem. In a community, different plants, animals, and other organisms interact with each other. Population-A population is a group of organisms of the same species that live in the same area.

Detailed explanation-4: -An ecological community is a group of actually or potentially interacting species living in the same location. Communities are bound together by a shared environment and a network of influence each species has on the other.
