12 Questions
Why do herbivores need to eat more compared to plants?
Due to the imbalance in C:N ratio between plants and herbivores
What is the primary source of energy for autotrophs?
Solar energy
What do detrivores feed on?
Non-living organic matter
Why do herbivores face substantial nutritional chemistry problems?
To compensate for the difference between food nutrient content and growth requirements
Which feeding category mainly preys on animals?
Carnivores
Why do plants form mutualistic associations with mycorrhizal fungi?
To obtain limiting nutrients from the fungi
What is the primary nutrient that mycorrhizal fungi provide to plants?
Phosphorus
Which of the following is a key characteristic of arbuscular mycorrhizal fungi?
They produce arbuscules, hyphae, and vesicles.
Why are plant cell walls, which are rich in cellulose and lignin, not easily digested by most animals?
Animals lack the necessary enzymes to break down these structural carbohydrates.
Which type of functional response is characterized by a linear increase in feeding rate at low food densities, followed by a slower increase at intermediate densities and a leveling off at high food densities?
Type 2
Which of the following animals is an example of the Type 1 functional response?
Baleen whale
What is the key characteristic of the Type 3 functional response?
Feeding rate is s-shaped, with the organism ignoring prey at low densities.
