Photosynthesis and Cellular Processes Quiz

What are trophic levels in an ecosystem?

• Trophic levels are the different species found in a habitat.
• Trophic levels are the types of plants in an ecosystem.
• Trophic levels refer to the physical space occupied by organisms.
• Trophic levels are the different levels in a food chain, representing the flow of energy from producers to various levels of consumers.

What percentage of energy is typically transferred from one trophic level to the next?

• 50%
• 10%
• 25%
• 5%

Which of the following is a limiting factor in an ecosystem?

• Temperature

• Predation

• Food availability

• All of the above

What is carrying capacity?

• Carrying capacity is the number of individuals that can be supported by a single resource.
• Carrying capacity refers to the total biomass of all species in an ecosystem.
• Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely.
• Carrying capacity is the minimum population size required for a species to survive.

What happens to matter as it moves through the trophic levels of an ecosystem?

• Matter is only transferred without any transformation.
• Matter is completely destroyed at each trophic level.
• Matter is transformed and transferred, with energy loss at each trophic level.
• Matter remains unchanged as it moves through trophic levels.

Which of the following organisms is at the highest trophic level?

• Herbivores like deer or rabbits.
• Primary producers like grass or algae.
• Apex predators such as great white sharks or lions.
• Omnivores such as bears or humans.

What is the purpose of photosynthesis?

• To create water as a byproduct.
• The purpose of photosynthesis is to convert light energy into chemical energy in the form of glucose, while releasing oxygen as a byproduct.
• To produce heat energy for plants.
• To absorb carbon dioxide from the atmosphere.

Which organelle is responsible for photosynthesis?

• Mitochondria
• Ribosomes
• Nucleus
• Chloroplasts

What are the products of cellular respiration?

• Oxygen, glucose, and heat
• Nitrogen, hydrogen, and glucose
• Carbon monoxide, ethanol, and energy
• Carbon dioxide, water, and ATP

What is the relationship between photosynthesis and cellular respiration?

• Photosynthesis and cellular respiration are unrelated processes that do not affect each other.
• Photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate energy.
• Cellular respiration produces glucose and oxygen, which are used in photosynthesis.
• Photosynthesis occurs only at night while cellular respiration happens during the day.
