The animals in the food web release _____________ into the environment, which plants then use for ___________.
Responses
A oxygen:respirationoxygen:respiration
B carbon dioxide:respirationcarbon dioxide:respiration
C water vapor:photosynthesiswater vapor:photosynthesis
D carbon dioxide:photosynthesis
B carbon dioxide:respirationcarbon dioxide:respiration
Option B: carbon dioxide:respirationcarbon dioxide:respiration
The answer to the question is D: carbon dioxide: photosynthesis.
To arrive at this answer, we need to understand the process of photosynthesis and how it relates to the food web.
During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose (a type of sugar) and oxygen. This process takes place in the chloroplasts of plant cells and requires the presence of chlorophyll (a green pigment).
Now, let's examine the given options:
A) Oxygen: respiration - While it is true that animals release oxygen through respiration, plants do not directly use this oxygen for their own processes like photosynthesis.
B) Carbon dioxide: respiration - Both animals and plants release carbon dioxide through respiration. However, plants do not use this carbon dioxide for their photosynthesis process. Instead, plants take in carbon dioxide from the environment to perform photosynthesis.
C) Water vapor: photosynthesis - Water vapor is released by plants through a process known as transpiration. However, this water vapor is not used by plants for photosynthesis. It is mainly involved in regulating the temperature and water balance of the plant.
D) Carbon dioxide: photosynthesis - This is the correct answer. Animals in the food web release carbon dioxide through respiration. This carbon dioxide, along with sunlight, water, and chlorophyll, is used by plants during photosynthesis to produce glucose and oxygen.
Therefore, the animals in the food web release carbon dioxide into the environment, which plants then use for photosynthesis.
