Relationship between living things and their environment?

Answer 1

Ecology is the relationship between living things and their environments. Plants need the soil, sunlight, and water to grow to be able to feed animals. Other, often larger animals eat the animals that feed on the plants. Scavengers and decomposers come along and eat the carcasses of animals, depositing feces into the soil that begins the cycle again.

Ecosystem - a group of living things in an area that interact with each other, together with their nonliving environment.

An ecosystem can be as tiny as a drop of pond water or a few square meters of a garden.

It can be as large as a forest or an ocean.

The entire Earth is also an ecosystem.

In an ecosystem, the different factors are interdependent. The plants, animals, and the nonliving parts of the ecosystem all interact with one another.

All the different organisms that live together in an area make up the living part, or community, of any ecosystem. A pond community has plants, fish, insects, frogs and turtles. In a forest ecosystem, the trees, birds, snakes, insects, and small animals make up a community.

The living things in the community are interdependent. In a pond community, frogs eat insects, and fish eat tadpoles. Some fish also eat plants as the insects do. In a forest ecosystem, insects and birds feed on plants. Other animals such as lizards feed on insects. Larger animals eat lizards.

The plants in the community are the source of food for the plant-eating animals. The other organisms feed on plant-eaters and on other animals. Animals in this community cannot live without plants, the same way plants cannot live without these animals. They depend on each other in order to survive.

All the living and nonliving things in an ecosystem must interact successfully in order for the ecosystem to survive. All the living things must be able to obtain food, water, and shelter from their environment. The plant and animal populations can reproduce and increase their numbers given the right conditions. Certain living and nonliving factors in the environment can stop population from increasing its size. These are called the limiting factors. The food, space, temperature, and disease are examples of limiting factors. Sometimes the growth of a population is limited as a result of its relationship with other organisms. Relationship between organisms include mutualism, commensalism, parasitism, predation, competition, and cooperation. These relationships are either beneficial or harmful to the interacting populations.
