Answer:

The correct answer is option A, Plants

Explanation:

Plants are the only species that take up the carbon dioxide and produces oxygen through the process of photosynthesis. They do not release CO2 directly into the environment. While human take up oxygen and produces carbon dioxide which is exhaled out through respiration. The factories and machine uses fossil fuels rich in carbohydrate which on burning produces carbon dioxide as an exhaustive gas.

What best explains why there's fewer secondary consumers than producers?

Alexandra [31]

The question is incomplete as it lacks te end part of the question. However, the missing part is as follows:

In the F2 generation, all possible combinations of these traits were expressed in ratios consistent with Mendelian inheritance. Identify the four dominant traits, and enter them in ALPHABETICAL order in the blanks provided. [x],[y],[z],[a].

Answer:

The correct answer is :

x)axial

y)full

z)round

a)violet

Explanation:

True breeding organisms are organisms that carry two same alleles of a particular trait or character either dominant or recessive. In this given case the two breeding plants have four distinct traits, round, terminal, violet, constricted in one parent and wrinkled, axial, white, full in other.

In f1 there would be only dominant alleles for these characters will be expressed, that is already given in the question-

round, axial, violet, and full

The alphabetical arrangement of the dominant alleles are-

x)axial

y)full

z)round

a)violet
