goldenfox [79]
The unknown type of corn had to be yellow.

There were offspring that were red and yellow.

The red corn only has recessive alleles (r and r) so, the yellow alleles( R) didn't came from this type.  They came from a yellow type corn.

And since the offspring were NOT all yellow (the dominant color) we know that the yellow corn was heterozygous for the color trait (Rr).

50% red (rr)
50% yellow (Rr)

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.
