c. omnivore
Omnivores are organisms that eat both plants (which makes them primary consumers) and animals (which makes them secondary consumers). Therefore, they can fulfill the roles of both secondary and primary consumers in a food web.

how does the interconnection of food chains in a food web contribute to a stability of an ecosystem?
a. it ensures that only one species is responsible for each trophic level.
b. it allows multiple organisms to share the same food source, providing alternative food options if one source is depleted
c. it limits the number of organisms that can occupy each tropic level.
d. it increases competition among species, leading to a decrease in population sizes

b. it allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
The interconnection of food chains in a food web creates a more complex network of feeding relationships, which enhances resilience and stability in an ecosystem. If one species or food source declines or becomes scarce, other organisms can still find alternative food sources, helping to maintain balance and prevent widespread disruption in the ecosystem.

if a primary consumer population decreases significantly in a freshwater ecosystem, what is the most likely immediate impact on a secondary consumers.
a. they will increase in number due to less competition
b. they will migrate to find new food sources
c. they will decrease in number due to a lack of food
d. they will switch to being primary consumers
a. they will increase in number due to less competition
b. they will migrate to find new food sources
c. they will decrease in number due to a lack of food
d. they will switch to being primary consumers
GPT-4o mini
c. they will decrease in number due to a lack of food.
If the population of primary consumers decreases significantly, secondary consumers will likely face a food shortage, leading to a decrease in their numbers as they struggle to find sufficient food to survive.

which of the following best explains why energy transfer in a food web is described as a pyramid?
a. energy is lost at each trophic level, with less energy available to organisms higher up in the pyramid
b. there are more producers than consumers in an ecosystem
c. tertiary consumers receive the most energy in an ecosystem
d. the shape of the pyramid represents the physical structure of ecosystems

GPT-4o mini
a. energy is lost at each trophic level, with less energy available to organisms higher up in the pyramid.
In a food web, energy is transferred from one trophic level to the next, but not all energy is passed on; a significant portion is lost as heat, through respiration, and metabolic processes. As a result, less energy is available to organisms at higher trophic levels, which is represented by the pyramid shape, with the widest part at the bottom (producers) and the narrowest part at the top (higher trophic level consumers).

answer the following questions based on pages 4-5 (the food web organizer & the freshwater ecosystem food web) and the information you have learned in this unit. which of the following is a type of fungus that acts as a decomposer?
a. phytoplankton
b. yeast
c. cory catfish
d. alligator
a. phytoplankton
b. yeast
c. cory catfish
d. alligator
GPT-4o mini
b. yeast
Yeast is a type of fungus that acts as a decomposer, breaking down organic matter. Phytoplankton are photosynthetic organisms, cory catfish are fish, and alligators are reptiles, none of which function as decomposers.

what percentage of energy from the sun do producers in a freshwater ecosystem get
a. 1%
b. 10%
c. 100%
d. 0.1%
a. 1%
b. 10%
c. 100%
d. 0.1%
GPT-4o mini
a. 1%
In general, producers (such as plants and phytoplankton) capture about 1% of the energy from the sun that reaches them and convert it into chemical energy through photosynthesis. This percentage can vary slightly depending on the ecosystem and conditions, but 1% is a commonly cited figure.
