Ecological Components Quiz

Living organisms like trees are biotic components in an ecosystem.

Seaweed, being capable of photosynthesis, is a primary producer in marine ecosystems.

Fox, being a predator that consumes herbivores, is an example of a secondary consumer in an ecosystem.

Lichen, being among the first to colonize barren landscapes, is an example of a pioneer species.

Biodiversity refers to the variety of different species present in an ecosystem.

Transpiration is the process where water vapor is released from plants into the atmosphere.

Decomposition is the process where decomposers break down dead organic matter into simpler substances.

A keystone species has a large impact on its environment, influencing the ecosystem disproportionately.

Climax communities exhibit high biodiversity, indicating a stable and mature ecosystem.

Decomposers primarily break down organic matter into simpler compounds, recycling nutrients in the ecosystem.

Trophic levels transfer energy and nutrients through the food chain in an ecosystem.

The mutualistic relationship involves bees pollinating flowers, benefiting both species.

Rainfall, a non-living factor, is an example of an abiotic component in a terrestrial ecosystem.

Watersheds play a crucial role in controlling erosion and sedimentation in an ecosystem.

Oxygen is not a greenhouse gas; greenhouse gases trap heat in the Earth's atmosphere.

Oligotrophic lakes have low nutrient content, contributing to their clear water and low productivity.

Nitrogen fixation is the process of converting atmospheric nitrogen into a form usable by plants.

Primary succession occurs on bare rock or soil, starting with pioneer species.
