Study Notes
Food Chains and Energy Flow
- In a food chain, one animal eats another animal or eats a plant, becoming part of the flow of energy.
- Energy from the Sun is passed from one organism to another through the food chain.
- Plants are producers, producing their own food using sunlight energy.
- Consumers, including carnivores, herbivores, and omnivores, obtain energy by eating other organisms.
Types of Consumers
- Carnivores: eat only animals (e.g., hawks, lions, spiders)
- Herbivores: eat only plants (e.g., zebra, horse, deer)
- Omnivores: eat both plants and animals (e.g., humans, ostriches, fire ants)
Food Chains in Different Habitats
- Aquatic habitats: plants and animals that live in or on water
- Terrestrial habitats: plants and animals that live on land
- Both aquatic and terrestrial habitats have producers, consumers, and decomposers
Producers
- Grasses, bushes, and trees are producers in savannas
- Producers create their own food using sunlight energy
- Producers are the first link in a food chain
Consumers in Different Habitats
- Desert habitats: adapted organisms that live in dry conditions
- Desert producers include grasses, wildflowers, and cactuses
- Desert herbivores include insects and small animals like rabbits
- Desert carnivores include snakes and coyotes
Energy Flow and Food Chains
- Energy flows from the Sun to producers, then to consumers
- Each food chain starts with a producer that uses sunlight energy
- Consumers obtain energy by eating other organisms in the food chain
