Q: Which equation best represents the total flight height for a crow dropping a whelk?

$$\text{Total flight height} = \text{drop height} \times \text{number of drops}$$

Q: Which equation best represents the photosynthesis process?

$$6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$$

Question 1

Which of the following best describes the difference between proximate and ultimate causation in animal behavior?

Accepted Answer

Proximate causation refers to the immediate physiological or environmental mechanisms that trigger a behavior, while ultimate causation refers to the evolutionary reasons for why the behavior exists.

Question 2

In the crow and whelk experiment, which variable is considered the independent (explanatory) variable?

Accepted Answer

Drop height (m)

Question 3

According to the optimal foraging model, what is the most likely reason crows prefer to drop whelks from approximately 5.23 meters?

Accepted Answer

It represents a tradeoff between minimizing energy expenditure and maximizing success rate.

Question 4

Which of the following is an example of a fixed action pattern?

Accepted Answer

A goose rolling an egg back into its nest whenever it sees an egg outside the nest.

Question 5

Which equation best represents the total flight height for a crow dropping a whelk?

Accepted Answer

$$	ext{Total flight height} = 	ext{drop height} 	imes 	ext{number of drops}$$

Question 6

Which of the following is a real-world example of mutualism?

Accepted Answer

Bees pollinating flowers while collecting nectar

Question 7

What is the main difference between fundamental and realized niche?

Accepted Answer

Fundamental niche is the potential range of conditions a species can tolerate, while realized niche is the range it actually occupies due to competition and other biotic factors.

Question 8

Which of the following best describes the energetic hypothesis in trophic structures?

Accepted Answer

Energy transfer between trophic levels is limited by the inefficiency of energy transfer, typically around 10%.

Question 9

Which of the following is a key adaptation that allowed seed plants to colonize land?

Accepted Answer

Production of seeds that protect and nourish the embryo

Question 10

Which structure in a flower is responsible for producing pollen?

Accepted Answer

Anther

Question 11

Which process is directly responsible for the movement of water from roots to leaves in vascular plants?

Accepted Answer

Transpiration

Question 12

Which equation best represents the photosynthesis process?

Accepted Answer

$$6	ext{CO}_2 + 6	ext{H}_2	ext{O} + 	ext{light energy} ightarrow 	ext{C}_6	ext{H}_{12}	ext{O}_6 + 6	ext{O}_2$$

Question 13

Which of the following is a limiting factor for primary production in most terrestrial ecosystems?

Accepted Answer

Availability of nutrients such as nitrogen and phosphorus

Question 14

Which of the following best explains why energy transfer between trophic levels is only about 10% efficient?

Accepted Answer

Most energy is lost as heat due to metabolic processes.

Question 15

Which nutrient cycle involves atmospheric fixation, assimilation by plants, and decomposition by bacteria?

Accepted Answer

Nitrogen cycle

Question 16

Which of the following best describes the role of stomata in plants?

Accepted Answer

Stomata regulate gas exchange and water loss through transpiration.

Question 17

Which of the following is a key feature of the angiosperm life cycle?

Accepted Answer

Double fertilization resulting in a zygote and endosperm

Question 18

Which of the following is an example of top-down control in a food web?

Accepted Answer

Predators regulate the abundance of herbivores, which in turn affects plant populations.

Question 19

Which of the following best describes the relationship between ecology and evolution?

Accepted Answer

Ecological interactions can drive evolutionary changes, and evolutionary adaptations can influence ecological relationships.

Question 20

A researcher observes that mosses have a life cycle dominated by the gametophyte stage. Which of the following best explains the significance of this observation?

Accepted Answer

The gametophyte is the main photosynthetic and reproductive stage in mosses.
