Mini Lesson

A habitat is the natural environment where an animal or plant lives. It supplies everything the organism needs to survive. Different animals have different habitat requirements, which is why a polar bear cannot live in a rainforest, and a dolphin cannot survive in a desert.

The Four Things a Habitat Provides

  • Food — plants to eat, prey to hunt, or decomposing matter.
  • Water — rivers, rain, dew, or moisture in food.
  • Shelter — trees, burrows, caves, or coral reefs.
  • Space — enough room to find food, reproduce, and move freely.

Types of Habitats

  • Forest — dense trees, moist soil, varied wildlife.
  • Ocean — saltwater, coral reefs, open water.
  • Desert — dry, sandy, extreme temperatures.
  • Wetland — muddy, water-logged, rich in reeds and water birds.
  • Grassland — flat, open, grasses, herds of large animals.
