Biotic and Abiotic in Ecosystems

Describe a predator-prey relationship in an ecosystem and explain its significance.

• A predator-prey relationship is when an organism feeds on plants for energy.

• A predator-prey relationship is when two organisms compete for the same food source.

• A predator-prey relationship is when two organisms work together to hunt for food.

• A predator-prey relationship is when one organism hunts and consumes another organism for food. This relationship is significant in maintaining the balance of the ecosystem by controlling the population of the prey species and preventing overgrazing or overpopulation.

Discuss the role of decomposers in the ecosystem and how they contribute to nutrient cycling.

• Decomposers break down dead organic matter and release nutrients back into the soil, contributing to nutrient cycling in the ecosystem.

• Decomposers break down living organisms and reduce nutrient availability in the soil.

• Decomposers contribute to the growth of plants by absorbing excess nutrients from the soil.

• Decomposers have no role in nutrient cycling and only serve to create waste in the ecosystem.

How does climate change impact biotic and abiotic factors in an ecosystem?

• Climate change has no impact on biotic and abiotic factors in an ecosystem

• Climate change only impacts abiotic factors in an ecosystem

• Climate change only impacts biotic factors in an ecosystem

• Climate change can impact both biotic and abiotic factors in an ecosystem.

Explain the dynamics of an aquatic ecosystem and how biotic and abiotic factors interact within it.

• The dynamics of an aquatic ecosystem involve the interactions between living organisms (biotic factors) and non-living elements (abiotic factors).

• The dynamics of an aquatic ecosystem are solely determined by abiotic factors such as temperature and water pH.

• Abiotic factors in an aquatic ecosystem do not play a role in supporting the life of biotic factors.

• Biotic factors in an aquatic ecosystem have no impact on the overall dynamics of the ecosystem.

How does the process of decomposition contribute to the overall health of an ecosystem?

• Decomposition provides essential nutrients for the growth of plants and helps in recycling organic matter.

• Decomposition only benefits a few select species in the ecosystem

• Decomposition has no impact on the overall health of an ecosystem

• Decomposition releases harmful toxins into the environment

Discuss the potential consequences of climate change on aquatic ecosystems.

• No impact on aquatic life

• Increase in biodiversity

• Potential consequences of climate change on aquatic ecosystems include increased water temperatures, ocean acidification, changes in precipitation patterns, and sea level rise.

• Decreased air pollution

Compare and contrast the roles of biotic and abiotic factors in shaping terrestrial and aquatic ecosystems.

• Biotic factors are non-living components, while abiotic factors are living organisms.

• Biotic factors only affect terrestrial ecosystems, while abiotic factors only affect aquatic ecosystems.

• Biotic factors are living organisms, while abiotic factors are non-living components that shape both terrestrial and aquatic ecosystems.

• Biotic and abiotic factors have no impact on shaping ecosystems.
