The answer would be <span>"A niche is the role an organism has in an ecosystem."</span> Because a niche is the position or 'job' an
organism has in an ecosystem. For example, the niche of certain
butterflies and bees is to pollinate flowers in an ecosystem which
allows them to reproduce.
The most likely dispersion pattern of the plants that grow from these seeds is random.
<u>Explanation:</u>
In a habitat, the pattern in which the seeds of the plants gets dispersed can be classified into three types They are random, uniform and clumped. The pattern of distribution of the seeds helps in determining the relation that exists between different members and their spaces in an ecosystem.
The dispersed seeds have an equal space of distribution and hence it is called as uniform distribution. In a random distribution the seeds get to disperse and grow wherever they fall. This happens because of wind. When wind blows they take the seeds with them and when they stop they will make the seeds to fall wherever they stop blowing. this is an example of random dispersion of seeds.
If hunted and sold, animals will have a lower chance of reproducing apart from not being there themselves, decreasing their population.
Having less species inhabiting an area, means less food for some predators. Which means that competition will occur among preators since food will be scarce.

<u>Phenylketonuria</u>
Explanation:
Phenylketonuria (PKU) is a type of a rare inherited metabolic disorder.
Etiology: PKU results from excessive accumulation of the amino acid phenylalanine in the body. Normally, phenylalanine will be converted to tyrosine (forms neurotransmitters) by the action of the enzyme phenylalanine hydroxylase.
Among people with PKU, a defect in the PAH gene which codes to synthesize this enzyme occurs which leads to the absence of this enzyme. So the phenylalanine which is normally present in dietary protein is not metabolized and gets accumulated. This gene is inherited by the child only if both the parents are with the defective PAH gene.
Symptoms: Stunted growth, behaviroral disturbances, learning difficulties, seizures, tremors etc.
Treatment: Basic treatment is to follow a diet which limits dietary sources of phenylalanine. High protein foods like meat, egg should be avoided. Children can be given PKU formula to supplement their nutritional needs.
