Answer:
b. ecosystems in a region, species in an ecosystem, and genes and alleles in a species.
Explanation:
Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.
I would say C.
I hope it’s right or u can individually search up each of those animals to check that they’re a secondary consumer.
The presented picture shows 4 trophic levels of the ecosystem.
The first level is made out of primary producers, plants. The second level is made out of herbivores that feed on the plants. The third level is made out of predators that eat herbivores.
The fourth trophic level is made out carnivores that eat other carnivores.
In our case, the only organism belonging to the fourth trophic level is the wolf.
Answer:
allele, changing, increasing
Explanation:
The allele that an organism inherits from its parents influence its phenotype. Phenotypes can also be influenced throughout an organism’s lifetime by changing the expression of particular genes. For example, increasing the expression of an allele will often accentuate that allele’s phenotype.
<em>Allele represents the alternate form of a gene. Hence, the allele inherited determines the phenotype of an organism.</em>
<em>The physical appearance of an organism is also influenced by gene regulation. A gene can be turn on/off as the the case may be and this will affect the phenotype.</em>
<em>Increasing the expression of an allele will accentuate or emphasize the phenotype the allele controls and vice versa.</em>
