use the food web to the left to answer the following questions: what are the 2 producers of the food web? what is the name given to the food web? or also known as? what are 3 primary consumers? what animal will receive the least energy? look at the energy pyramid to the right to determine whether each statement is true or false. t or f energy decreases as it is lost as heat to the environment. t or f energy is transferred since it is produced by organisms at each level. t or f energy is never available because it is used up by primary producers. why is the number of organisms in this food pyramid smaller at the top? approximately __% of energy is passed on to the next trophic level. which activity demonstrates energy being transferred from one trophic level to another in an ecosystem? a watering a plant b reproducing with a mate c eating leaves from a plant explain why you chose your answer

Question

Accepted Answer

### 1. “Energy decreases as it is lost as heat to the environment” (True or False)
# Brief Explanations:
In an energy pyramid, energy transfer between trophic levels is inefficient. Most energy is used for metabolic processes (like respiration) and lost as heat. So energy decreases up the pyramid as heat loss occurs.
# Answer:
True (T)

### 2. “Energy is transferred since it is produced by organisms at each level” (True or False)
# Brief Explanations:
Organisms at higher trophic levels don’t produce energy—they obtain it by consuming lower levels. Energy originates from the sun (captured by producers). So this statement is false.
# Answer:
False (F)

### 3. “Energy is never available because it is used up by primary producers” (True or False)
# Brief Explanations:
Primary producers (plants) capture solar energy and make it available to the food chain. Energy is transferred (not “used up” in a way that makes it unavailable—they pass energy to consumers). So this is false.
# Answer:
False (F)

### 4. “Why is the number of organisms in this food pyramid smaller at the top?”
# Brief Explanations:
Energy decreases with each trophic level (only ~10% transferred). Top-level organisms need more energy per individual, but less total energy is available. So fewer organisms can be supported.
# Answer:
Because energy decreases at each trophic level (only ~10% transferred to the next level), so there’s less energy to support many top - level organisms.

### 5. “Approximately __% of energy is passed on to the next trophic level.”
# Brief Explanations:
The 10% rule in ecology states that about 10% of energy from one trophic level is passed to the next (the rest is lost as heat, used for metabolism, etc.).
# Answer:
10

### 6. “Which activity demonstrates energy being transferred from one trophic level to another in an ecosystem? A. watering a plant B. reproducing with a mate C. eating leaves from a plant”
# Brief Explanations:
- Option A: Watering a plant is adding water (not energy transfer between trophic levels).
- Option B: Reproducing is about passing genes, not energy between trophic levels.
- Option C: Eating leaves means a consumer (e.g., herbivore) gets energy from the producer (plant), transferring energy between trophic levels.
# Answer:
C. eating leaves from a plant

### 7. “Explain why you chose your answer (for the above multiple - choice question)”
# Brief Explanations:
Eating transfers energy: the plant (producer, lower trophic level) has stored energy (from photosynthesis). When an organism eats the plant, that energy moves to the consumer (higher trophic level). Watering (A) is not energy transfer between trophic levels, and reproducing (B) doesn’t transfer energy between levels.
# Answer:
Eating leaves (C) transfers energy from the plant (producer, lower trophic level) to the eater (consumer, higher trophic level). Watering (A) is not energy transfer between trophic levels, and reproducing (B) doesn’t involve energy transfer between different trophic levels.
