Questions covering how energy moves through ecosystems via food chains, food webs, and trophic levels. Focuses on energy transfer, efficiency, and ecological relationships.
Energy flow in an ecosystem is unidirectional, moving from producers to consumers and eventually lost as heat.

Food chains do not always begin with decomposers; they usually start with producers like plants.

Food chains do not exist independently; they interconnect with other food chains to form a food web.

Grazing food chains begin with living plants, while detritus food chains start with dead organic matter that decomposers break down.

In a forest ecosystem, the detritus food chain is more dominant because a large amount of energy flows through decomposers.

The detritus food chain starts with dead organic matter, which is broken down by decomposers before passing energy to consumers.

A grazing food chain begins with producers (plants) and moves up to herbivores (goat) and then to carnivores (man).

The detritus food chain plays a vital role in nutrient recycling by decomposing dead organic matter into usable forms.

The detritus food chain begins with dead organic matter, which is broken down by decomposers before being passed on to consumers.
