4 types of primary consumers in a forest

1. Herbivores: These are animals that primarily feed on vegetation such as leaves, grass, fruits, and nuts. Examples include deer, rabbits, and squirrels.

2. Insectivores: These are animals that consume insects as their primary food source. They may also eat other small invertebrates like worms and spiders. Examples include birds, amphibians, and some small mammals like shrews.

3. Frugivores: These are animals that specialize in eating fruits. They play a crucial role in seed dispersal by consuming fruits and then depositing the seeds through their feces in different locations. Examples include birds, monkeys, and some bats.

4. Granivores: These are animals that feed primarily on seeds. They have specialized digestive systems that allow them to grind and break down tough seed shells to extract the nutrients inside. Examples include squirrels, mice, and some birds.
