Instinctive behaviors are innate and do not need to be learned. Monarch migration is a classic example of an instinct, whereas learning to sit is a learned behavior.

Omnivores are animals that have a diet consisting of both plant and animal matter. Herbivores eat only plants, and carnivores eat only meat.

The sun provides the light energy that plants use for photosynthesis, which is the base of almost all food chains on Earth.

Bark serves as a protective outer layer for a tree, much like skin serves as a protective outer layer for a human.

A life cycle describes the series of developmental stages an organism goes through from the beginning of its life (egg/birth) to adulthood and reproduction.

While these groups have many differences, birds, amphibians, reptiles, and many fish species reproduce by laying eggs.

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Producers, such as plants and algae, are organisms that produce their own food using sunlight through photosynthesis.

Herbivores are animals that have a diet consisting exclusively of plants.
