I believe the correct response would be C. Production of antibodies.
Answer:
Yes (It's more inefficient)
Explanation:
in ecology there are things called primary producers (plants) that are eaten by primary consumers (cows and chickens) and then there are humans, secondary consumers, that eat cows and chickens for energy.
The further we move from eating primary producers the more inefficient we become in consuming energy. Meaning, it requires a lot more natural energy consumption to support a human that lives on meat only as compared to a human that eats plants only. this inefficiency only magnifies when communities practice unsustainable food methods.
There are sustainable ways to eat meat, but (at least in the US) our current conventions of meat production are unsustainable and environmentally destructive.
- The environment needs to change in order to natural selection to occur.
Reason:
Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2. Population has some genetic variations.
Reason:
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:
mutation and random mating between organisms
3. Nature select organism with specific traits to survive and reproduce.
Reason:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

I'm pretty sure it's a community.
Hope this helps :)
