What type of consumer eats only plants?

Herbivores are the type of consumers that eat only plants. This classification is crucial in understanding ecological relationships and food chains. Herbivores obtain their energy from consuming various plant materials, including leaves, stems, fruits, and roots. They play a vital role in ecosystems as primary consumers, transferring the energy captured by plants through photosynthesis up the food chain to higher trophic levels, such as carnivores.

The other options represent different types of consumers in the ecosystem. Carnivores are organisms that primarily consume other animals, omnivores eat both plants and animals, and decomposers break down organic material from dead organisms, recycling nutrients back into the soil. Understanding these roles helps in comprehending the dynamics of ecological interactions and energy flow.
