Front

What type of relationship exists between biting flies and zebras?

Back

Parasitism: A relationship where one organism benefits at the expense of another.

Front

What is the role of primary producers in an ecosystem?

Back

Producing energy for themselves and consumers: Primary producers, like plants, convert sunlight into energy through photosynthesis.

Front

What is a potential impact of ocean acidification on coral reefs?

Back

Coral bleaching and reduced biodiversity: Ocean acidification can harm coral reefs, leading to loss of color and species.

Front

Which law explains the loss of energy as heat in a food chain?

Back

Second law of thermodynamics: This law states that energy transformations are not 100% efficient, leading to energy loss as heat.

Front

What can decrease ecosystem resilience?

Back

Habitat destruction: The loss of natural habitats reduces the ability of ecosystems to recover from disturbances.

Front

Define mutualism in ecological terms.

Back

Mutualism: A symbiotic relationship where both species benefit from the interaction.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem productivity and stability, allowing for better resilience to changes.

Front

Explain the concept of energy flow in an ecosystem.

Back

Energy flow: The transfer of energy from one trophic level to another, typically decreasing at each level due to energy loss.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is the impact of invasive species on native ecosystems?

Back

Invasive species can outcompete native species for resources, leading to declines in biodiversity.
