Ecological Relationships and Energy Transfer

Front

What is an ecological relationship?

Back

An ecological relationship refers to the interactions between different species in an ecosystem, including predation, competition, mutualism, and commensalism.

Front

Define producers in an ecosystem.

Back

Producers are organisms, typically plants and algae, that can make their own food through photosynthesis, converting sunlight into energy.

Front

What is energy transfer in an ecosystem?

Back

Energy transfer in an ecosystem refers to the movement of energy through food chains and food webs, from producers to consumers and decomposers.

Front

What percentage of energy is typically transferred from one trophic level to the next?

Back

About 10% of energy is transferred from one trophic level to the next, with the rest lost as heat.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores are primary consumers that eat producers (plants) and transfer energy from the plant level to the animal level in the food chain.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis and respiration.

Front

What is the significance of zooplankton in aquatic ecosystems?

Back

Zooplankton are crucial as they serve as primary consumers, feeding on phytoplankton and transferring energy to higher trophic levels.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the impact of plastic pollution on marine ecosystems?

Back

Plastic pollution can lead to the ingestion of plastic by marine animals, causing starvation, injury, and death, disrupting the food web.

Front

What is mutualism?

Back

Mutualism is a type of ecological relationship where both species benefit from the interaction, such as bees pollinating flowers.
