Habitat is really important for how living things interact with each other. The kind of habitat they live in affects where species are found, how many there are, and how they interact with one another. We can break these interactions down into four main types: predation, competition, mutualism, and symbiosis.

1. Predation:

   • Predators need specific habitats to hunt and raise their young. For example, about 60% of all bird species nest in forests. This affects how many birds there are since their hunting influences bird populations.

2. Competition:

   • Living things often compete for important resources like food, water, and living space. The type of habitat plays a big role in this. In places like tropical rainforests, competition can be really intense. For example, around 30% of plant species fight for sunlight, which leads to them finding different ways to survive.

3. Mutualism:

   • Some species form relationships where both sides help each other. A great example is in coral reefs. Here, tiny organisms called zooxanthellae provide nearly all the energy corals need. This shows how much they depend on their habitat.

4. Symbiosis:

   • Habitats also create the right conditions for symbiotic relationships. A well-known example is lichens, which are made up of algae and fungi. These usually grow in places that have enough moisture and light, covering about 8% of the Earth's surface.

In short, habitats greatly influence how living things interact with each other. This affects the balance of ecosystems and the variety of life we see. Understanding these connections is important for protecting nature and doing ecological research.
