Producers in a Food Chain

• Producers, also known as autotrophs, are organisms that make their own food through photosynthesis or chemosynthesis.

Types of Consumers in a Food Chain

• Herbivores are consumers that eat only plants for their energy.
• Carnivores are consumers that eat only animals for their energy.
• Omnivores are consumers that eat both plants and animals for their energy.

Omnivores in a Food Chain

• Omnivores are organisms that eat both plants and animals in a food chain.

Decomposers in a Food Chain

• Decomposers, such as bacteria and fungi, break down dead organic matter into simple nutrients that can be reused by producers.

Aquatic vs. Terrestrial Food Chains

• Aquatic food chains occur in water ecosystems, such as oceans, rivers, and lakes, and involve aquatic organisms.
• Terrestrial food chains occur on land and involve terrestrial organisms.
• The main difference between aquatic and terrestrial food chains is the type of organisms involved and the environment in which they exist.
