Answer:
Step-by-step explanation:
An ecosystem is a biological community of interacting organisms and their physical environment. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. Plants are then eaten by animals, which are in turn eaten by other animals, and so on. The energy that is not used by the organisms is released back into the environment as heat.
Ecosystems can be found in a variety of sizes and shapes. A small ecosystem might be a pond, while a large ecosystem might be a forest or a desert. Ecosystems can also be found in a variety of habitats, such as the land, the ocean, or the air.
Ecosystems are important because they provide us with many of the things we need to survive, such as food, water, and clean air. They also help to regulate the climate and protect us from natural disasters.
Here are some examples of ecosystems:
A pond ecosystem is made up of the plants and animals that live in a pond, as well as the water and the soil.
A forest ecosystem is made up of the trees and other plants that grow in a forest, as well as the animals that live in the forest, such as birds, deer, and bears.
A desert ecosystem is made up of the plants and animals that live in a desert, as well as the sand and the rocks.
