Matter moves through the biosphere by being cycled through various organic and inorganic stages. They are neither created nor destroyed. The biosphere is known as a closed system so no elements can escape. They are continually being recycled.<span>
</span><span>The flow of energy moves through living organisms via the food chain. A food chain is a diagram which shows how every living thing gets energy to live. Plants use the sun, nutrients in the soil and water to generate energy. Herbivores eat the plants to generate energy to survive. Carnivores eat the herbivores to generate energy. </span>
I believe it is D. the genetic variations are in the phenotype of the organism. The reason why I say this is because the phenotype is the physically noticeable characteristics in an organism, this allows them to mutate differently and only the ones who are fit enough and have the best phenotypes will survive.
Answer: D. The fungus and bacteria organisms are obtaining the energy they need by decomposing organic matter like dead trees and old apples.
Fungi is the primary decomposer of biological waste in forest ecosystem. Fungi grows on the branching network of hyphae which provide it more penetration potential towards the litter. Wood decaying fungi has enzymes required for decomposition of lignin, a chemical substance found in wood. Fungi decompose organic matter by releasing enzymes which breaks down the decaying matter, after that they absorb the nutrients in the decaying material. The left residue in the organic matter includes sugars and amino acids are degraded and decomposed by the bacteria.
Answer:
You did not post the ecosystem involved but below is an explanation of what a tertiary consumer is.
A tertiary consumer is an organism that feeds on other consumers, specifically primary and secondary consumers. They are often carnivores like hawks,owls, and sharks.
In the attachment below, the owl is the tertiary consumer. It mainly feeds of the primary consumers (mouse and rabbit) and the secondary consumer (snake).
9%
Why?
The frequency for allele a is 30% or 0.3. Let's call this frequency p.
p^2 would then represent the frequency of genotype aa (this is is derived from the formula p^2+2pq+q^2=1 where p and q represent alleles a and A respectively. So p^2=aa, pq=Aa and q^2=AA)
0.3^2=0.09 or 9%
