A.hazard
B.satellite
C.geologic
D.topographic
The answer is; C
Most often some ancestral characters are preserved in an organism's development hence can be used to study evolutionary relationships. One of these features is the gill slits in embryos. These have been used to postulate that all land organisms, that exhibit gill slits in their embryonic development, emanated from a common fish ancestor. In humans, these gill slits later develop in the pharyngeal.
b. Carbon is found in the grass and is passed from one level to the next in this food web.
c. All living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere.
d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
Answer:
The correct answer would be option D.
In any food web, the inorganic carbon from the atmosphere is incorporated into the organic matter by the process of photosynthesis.
Autotrophs perform photosynthesis and fix carbon obtained from carbon dioxide into the glucose or organic matter with the help of chlorophyll and in the presence of sunlight.
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
