Answer:
D) Because it can share four electrons in covalent bond.
Explanation:
The correct option is Option D.
Because it can share four electrons in covalent bond.
All other are incorrect because,
A = it can share four electrons in ionic bond.
Carbon share its electron and form covalent bond. It can not form ionic bond.
B = Because it can share six electrons inmetallic bond.
It is also incorrect because metallic bond is only formed by the metals and also there are only 4 valance electrons in carbon not six.
Option C = Because it can share four electrons in hydrogen bonds.
It is also incorrect because carbon can not form hydrogen bonds.

Explanation:
A trophic level is a set of organisms who all have similar nutritional needs. In a food web, secondary consumers, such as fox and birds of prey, are on the same trophic level. How do different populations from the same trophic level interact? Different populations on the same trophic level can compete for food.
Tolerance range refers to the range of conditions of the external environment an organism is able to withstand. The population size of a certain species can be lowered if conditions are outside optimum range. The population is lowered because the organisms cannot survive if there is too much or too little of a factor.
