Ecology & Energy (photosyn & respiration)

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆

Front

What is respiration in living organisms?

Back

Respiration is the biochemical process in which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What is the equation for cellular respiration?

Back

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)

Front

Define carrying capacity in an ecosystem.

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably over time.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first, then slows as it approaches the carrying capacity of its environment.

Front

What is the difference between parasitism and mutualism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, while mutualism is a relationship where both organisms benefit.

Front

What is an example of a food chain?

Back

Grass → Rabbit → Fox.

Front

What role do producers play 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.
