Tropic Levels
    Level 1: Plants and algae make their own food and are called primary producers.
    Level 2: Herbivores eat plants and are called primary consumers.
    Level 3: Carnivores which eat herbivores are called secondary consumers.
    Level 4: Carnivores which eat other carnivores are called tertiary consumers.
    Level 5: Apex predators which have no predators are at the top of the food chain.

In tropical rain forests:

The first level is plants. About 40% of all plants live in this biome.
The second level of the food web is herbivores. Small animals such as ants and other insects and larger animals like possums and tree kangaroos eat the leaves of plants and the plants' fruits and snails, , fish, small reptiles, frogs, beetles and spiders,
The third level of the food web is small meat eaters. Animals such as frogs, snakes, rodents, owls, platypuses and others feed on smaller animals such as insects to survive.
The fourth level of the food web is large carnivores. These animals eat both meat as well as plants. For example, crocodiles, pythons and dingoes fall into this category. The term for those who eat both meats and plants is omnivores.
The fifth level of the food web is hunters and predators. Large fierce animals such as jaguars, tigers, crocodiles, vultures, owls and eagles fall into this category, plus humans living in the rainforest.

There are always many more in the first level than in the second. More in the second than in the third. More in the third than in the fourth and more in the fourth than in the fifth.That is because the upper levels can only support a certain number.
