Study Notes

Without the sun, Earth would be dark, freezing cold, and devoid of life.
The sun is the primary source of energy for all living things, and life on Earth would not be possible without it.

A food chain represents a series of organisms, each relying on the previous one for food.
Energy is transferred from one living thing to another through a food chain.

Producers, such as plants, make their own food through photosynthesis.
Photosynthesis uses carbon dioxide, water, and sun energy to produce oxygen and glucose.
Glucose is a crucial energy source for other organisms in the food chain.
Producers are the first to receive energy from the sun, and a large number of them are necessary to support the rest of the food chain.

As you move up the food chain, less energy is passed on to each level.
Secondary consumers eat primary consumers and/or producers.
Omnivores eat both plants and animals, while carnivores eat only animals.
Examples of secondary consumers include bears, rats, and fish.
Tertiary consumers eat secondary consumers, and are typically large, meat-eating predators.
Examples of tertiary consumers include lions, sharks, owls, and humans.
These top consumers use most of their energy, which is why food chains generally stop at this level.
Top consumers play a crucial role in preventing overpopulation in ecosystems.
