How do global systems interact to affect ecosystems?
miskamm [114]

is a functional unit that results from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that form a unitary whole.  Ecosystems vary in size.  They can be as small as a puddle, or as large as the earth itself.  Basically, any living and non-living things interacting together can be considered an ecosystem.  Within each ecosystem, there are habitats that vary in size.  A habitat is a place where a population lives.  A population is a group of living organisms of the same kind living in the same place at the same time.  Natural ecosystems are made up of abiotic factors such as air, water, rocks, and energy and biotic factors such as plants, animals, and microorganisms.

Crawfish are shelled organisms that live in shallow freshwater rivers. They can have antennae of different lengths. Two parents
vredina [299]

The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.

The gene determines the amount of protein to be present in the antenna to determine its length.

Explanation:

Data given:

Two crawfish parent = medium length antennae, genotyoe Ll

One offspring = short antenna, genotype ll

one offspring = long antennae, genotype LL

The traits in offspring is shown as:

       L    l

L   LL    Ll

l   Ll     ll

The proportion of allele present in the gene determined the length of the antenna in crawfish.

The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
