Ecology

Ecology is the study of living things and how they interact with each other and with the non-living parts of their environment. It studies these relationships wherever there's life, from the African savanna (right) to coral reefs in tropical oceans (left).

๐Ÿ“– In short

Ecology studies how living things live together and with the place they live in: water, air and soil. Every living thing needs others: plants need sun and soil, rabbits eat plants, and foxes eat rabbits.

๐Ÿคฉ Did you know?

  • Scientists who study the environment are called โ€œecologistsโ€.
  • On an American island the number of moose rose sharply and then fell, teaching scientists a lot about balance.
  • Bacteria and fungi are very important because they return substances to the soil.
  • All living things are connected like a big web.

๐ŸŒŸ The food chain

The food chain starts with plants, which make their food from sunlight, then a plant-eating animal eats them, and a meat-eating animal eats it. When living things die, bacteria and fungi break them down and they become food for the soil again.

๐Ÿ” Balance

Nature has a delicate balance: if wolves disappear, for example, deer and moose multiply and eat all the plants, and the forest suffers. If the wolves come back, the balance returns.

๐Ÿ’ก Habitat

Every living thing has a habitat that suits it: fish in water, camels in the desert, polar bears on the ice. If the habitat changes or is destroyed, it becomes hard for the creature to survive.

๐ŸŽฏ People and the environment

People are part of the environment, and what they do affects it: pollution and cutting down trees harm it, while farming, recycling and protecting animals help preserve it.
