Imagine an ecosystem such as this pond. It is a freshwater pond with perch, bass, ducks, crayfish, frogs, and sometimes a visiting water snake or two. It has algae and water plants. Use this information to answer the following two questions.
Note: Fir trees are present in this ecosystem. In the ecosystem described in the image above, all of the following are biotic factors that would affect it except
A. temperature
B. hawks
C. beavers
D. fir trees
In the ecosystem described in the image above, all of the following are abiotic factors that would affect it except
A. temperature
B. rainfall
C. type of soil
D. water snakes
The correct answers are:
All of the following are biotic factors that would affect the ecosystem described, except D. fir trees. Fir trees are not mentioned as part of the pond's inhabitants or visitors, so they would not directly affect the animals and plants in the pond.
All of the following are abiotic factors that would affect the ecosystem described, except D. water snakes. Water snakes are living organisms and therefore belong to the biotic factors category. Temperature, rainfall, and soil type are all non-living or physical factors that can influence the survival and behavior of the organisms in the pond.
A. temperature would affect the ecosystem because if it gets too hot, the perch might start ordering lemonade and the ducks might put on tiny sunscreen hats.
B. hawks would affect the ecosystem because if they start hunting, the ducks might have to hire a bodyguard and the frogs might need to take self-defense classes.
C. beavers would affect the ecosystem because if they start building dams, the frogs might have to audition for a new musical called "Hop Over the Dam" and the crayfish might need to learn construction skills.
D. fir trees would not affect the ecosystem because even though they might sway in the wind and provide shade, I don't think they'll be forming a boy band with the frogs anytime soon.
In the ecosystem described, all of the following are biotic factors except for:
D. Fir trees
Explanation: Biotic factors refer to living components of an ecosystem. In this case, the perch, bass, ducks, crayfish, frogs, algae, water plants, and visiting water snakes are all living organisms or organisms that exist temporarily within the ecosystem. However, fir trees are not mentioned as part of the ecosystem, so they would not be considered a biotic factor affecting it.
In the ecosystem described, all of the following are abiotic factors except for:
D. Water snakes
Explanation: Abiotic factors refer to non-living components of an ecosystem. In this case, temperature, rainfall, and the type of soil are all environmental factors that can impact the ecosystem but are non-living. However, water snakes are mentioned as part of the ecosystem, which makes them a biotic factor, not an abiotic one.
To answer the first question, we are looking for something that is not a biotic factor in the ecosystem described. Biotic factors are living organisms that can influence an ecosystem. The options given are: A) temperature, B) hawks, C) beavers, D) fir trees.
In order to determine which of these is not a biotic factor, we need to understand what biotic factors are. Biotic factors include all the living organisms in an ecosystem, such as the perch, bass, ducks, crayfish, frogs, and water snakes mentioned in the description. Fir trees are also mentioned, so they do fall under the category of biotic factors. Therefore, the answer should not be D) fir trees, as it is a biotic factor.
To answer the second question, we need to identify an abiotic factor that would not affect the ecosystem described. Abiotic factors are non-living elements that shape an ecosystem. The options given are: A) temperature, B) rainfall, C) type of soil, D) water snakes.
In the given pond ecosystem, all the options except D) water snakes are abiotic factors. Temperature, rainfall, and the type of soil are all non-living elements that can affect the ecosystem's dynamics. Water snakes, on the other hand, are living organisms and therefore classified as biotic factors.
Therefore, the final answer the first question is D) fir trees, and the answer to the second question is D) water snakes.
