The environment is studied at different levels & stages.
Biosphere: The biosphere is the zone in which life exists. It consists of the atmosphere& the hydrosphere alongwith the earth surface where living beings live.
The biome is a community of plants and animals (flaura & fauna).
Community: A community is a group of people/living beings who live in a specific location. It is used to describe two or more populations of different species that exist at same place.
Population: A population is the multiple individuals or living organisms of a single species that live in an area.
The populations are formed by lalrge number of groups of organisms.
Group of populations form communities. The group of all communities form a biome, which exist in the biosphere.

To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:
R= tall stalk
r= short stalk
The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.
Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.
Answer:
It will increase the grass population.
It will decrease the snake population.
It will increase the grasshopper population
The scrotum is a sac of skin that hangs from the body at the front of the pelvis, between the legs. It sits next to the upper thighs, just below the penis. The scrotum contains the testicles
