what is the Study of the interactions of organisms with one another and with their environment?
Answer:
The study of how organisms interact with each other and with their environment is called ecology.
Explanation:
Ecology studies ecosystems, which are areas made up of both living and nonliving factors that interact with each other constantly. Within an ecosystem, there is a community of living things and these are the biotic factors. There are also many nonliving factors, called abiotic factors, and these include the temperature, amount of sunlight, weather and wind, precipitation, and pH of water. The living organisms interact with and depend on each other for food, and they also interact with the environment. For example, the amount of sunlight and precipitation in an area affects the plant life that grows there. This in turn determines the types of animals that are able to survive in that particular environment.
