Food Chain in the Forest

Vocabulary flashcards covering the components, trophic levels, energy flow, and decomposer cycle of a forest food chain.

Food Chain

A linear sequence of organisms through which energy and nutrients flow as one organism feeds on another within an ecosystem.

Sun (Solar Energy)

The primary and ultimate source of energy that powers the forest ecosystem, enabling primary producers to carry out photosynthesis.

Producer (Grass)

An autotrophic organism that manufactures its own food by absorbing energy directly from the sun, forming the base of the food chain.

Primary Consumer (Rabbit)

An herbivorous organism that directly feeds on autotrophic producers (grass) to obtain chemical energy.

Secondary Consumer (Wolf)

A carnivorous organism that preys upon and consumes primary consumers (herbivores like rabbits).

Tertiary Consumer (Tiger)

An apex carnivore occupying a higher trophic level that preys on secondary consumers (such as wolves).

Forest Food Chain Sequence

The trophic progression shown in the forest ecosystem: $\text{Sun} \rightarrow \text{Grass} \rightarrow \text{Rabbit} \rightarrow \text{Wolf} \rightarrow \text{Tiger}$.

Decomposers (Fungi / Mushrooms)

Organisms that break down dead and decaying organic matter, transforming complex organic compounds into essential inorganic nutrients for the soil.

Leaf Litter (Detritus)

Fallen dead plant matter on the forest floor that serves as organic fuel and habitat for saprotrophs and decomposers.

Nutrient Cycling

The circular ecological process whereby decomposers release nutrients from dead biomass back into the soil, nourishing new plant seedlings and restarting the producer cycle.

Trophic Level

The hierarchical position an organism occupies in a food chain, defined by its feeding relationship and distance from the primary energy source.
