Producers are organisms that make their own food. Plants would be an example. Primary consumers would be those that eat producers(plants,algae). Secondary consumers are animals that eat primary consumers. Herbivores are animals that only eat plants. Carnivores are those that only eat meat and don’t eat plants. Omnivores are those that eat both meat and plants. De composers are those that decompose organic material like dead animals. The herbivores here are the kangaroo rats,grasshoppers and bunny’s. The carnivores here are the hawk,lizard,tarantula and rattlesnake. I don’t think there is an omnivore. And the only decomposed here is the bacteria. As it decomposes the bodies of the animals when they are dead.
The shift away from each other because of the earth tectonic plates. Hope this helps :)
Feedback mechanism
Feedback mechanism refer to a condition where
every parts of the system is affecting each other, creating one
cause-and -effect notion within the system. Feedback mechanism divided
into 2, positive feedback mechanism and negative feedback mechanism
Answer:
A. 0
Explanation:
Both red-green color blindness and and shape of hairline are independently assorting genes.
Red-green color blindness is X-linked recessive while hairline shape is autosomal dominant.
The man who has widow's peak had a father with straight hairline. This means that the man is heterozygous for the trait.
Assuming hairline shape is represented by S. A heterozygous widow's peak man will have a genotype of Ss. A straight hairline woman will have a genotype of ss.
Assuming the allele for colour blindness is c. A normal vision man will have the genotype while a color blind woman will have the genotype .
x
<em>The man does not have the color blind allele and a daughter will need two color blind alleles (one from the father and the other from the mother) in order to show the trait.</em>
<em>This means that the probability of the couple producing a color blind daughter is 0. Hence, the chance that any daughter the couple has will be color blind with a straight hairline is also 0.</em>
The correct option is A.
