Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, reducing its concentration.

How does a decrease in the sea otter population affect the marine ecosystem?

Back

A decrease in the sea otter population leads to an increase in the sea urchin population, which in turn causes a decrease in the kelp population.

What is the impact of reduced ground cover on an ecosystem?

Back

The ecosystem becomes less stable due to a decrease in energy available from producers.

Front

How much energy is typically transferred from producers to herbivores in an ecosystem?

Back

Approximately 10% of the energy incorporated by producers is transferred to herbivores; for example, if producers incorporate 12,000 kJ, herbivores would incorporate about 1,200 kJ.

What is secondary succession?

Back

Secondary succession is the process of ecological recovery that occurs in an area where soil is already present, such as after a wheat field is cleared.

What is 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.

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food, typically through photosynthesis, and form the base of the food chain.

What is the significance of energy transfer in food webs?

Back

Energy transfer in food webs is crucial for understanding how energy flows through an ecosystem, with only a small percentage of energy being passed from one trophic level to the next.

What are the effects of oil spills on marine life?

Back

Oil spills can severely impact marine life, affecting organisms at various trophic levels, particularly those that rely on the surface of the ocean.

Front

What is the relationship between producers and consumers in an ecosystem?

Back

Producers convert solar energy into chemical energy, which is then consumed by herbivores (primary consumers) and subsequently by carnivores (secondary consumers).
