The correct answer is: D. Primary succession occurs in a habitat that has never been colonized by any species before.
Ecological succession can be defined as ae process of change in the species structure of an ecological community over time. There are two types of succession:

• Secondary succession –formed after a disruption of a pre-existing community.
The death rate will increase
Answer:
A population of rabbits
Explanation:
Biomass is the weight of every organism in the species combined together.
Rabbits are primary consumers. They obtain more energy from the food they eat than foxes do. This is because foxes are secondary consumers. There will be fewer foxes in the ecosystem than rabbits.
The weight of all the rabbits in an ecosystem will be more than the weight of all the foxes in the same ecosystem.
1. Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. Multiply each of the atomic weights by the amount of atoms of each element contained in the compound. Add up the results to obtain the molar mass: 1 + 14 + (16 x 3) = 63 gr/mole.
2. In one molecule of sodium sulfate, or Na2 SO4, there are seven atoms in all.
3. Magnesium dichloride is a magnesium salt comprising of two chlorine atoms bound to a magnesium atom. It is a magnesium salt, an inorganic chloride and a magnesium halide.
