What is the energy transfer efficiency from producers to tertiary consumers?

Back

Energy transfer efficiency is low; typically only about 10% of energy is transferred from one trophic level to the next. If a producer has 300 kcal, a tertiary consumer would receive approximately 0.3 kcal.

Front

How are photosynthesis and cellular respiration related?

Back

Photosynthesis and cellular respiration are opposite reactions. The products of cellular respiration (carbon dioxide and water) are the substrates (reactants) for photosynthesis, and vice versa.

Front

What type of symbiotic relationship is exemplified by barnacles attaching to whales?

Back

This relationship is called commensalism, where one organism benefits (barnacles) while the other (whale) is neither helped nor harmed.

Front

Which elements are involved in photosynthesis and cellular respiration?

Back

The elements involved are Carbon (C), Hydrogen (H), and Oxygen (O).

Front

What type of symbiotic relationship is represented by mistletoe extracting nutrients from a spruce tree?

Back

This relationship is called parasitism, where one organism (mistletoe) benefits at the expense of the other (spruce tree).

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, primarily converting carbon dioxide and water into glucose and oxygen.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship where both organisms benefit from the interaction.
