The competitive exclusion principle states that two organisms cannot fill similar niches. select the best answer from the choices provided t f

True

Explanation:

An ecological niche can be define as the functional role played by the organism in an ecosystem so as to lead it's life cycle, grow, survive and reproduce. Like the resources used by the organism like food source, water source, habitat, type of mating season chosen and others.

In accordance to the competition exclusion principle, when two species or organisms having the same ecological niche, thriving for the same kind of resource, and lives in a same region or ecosystem, then the one which is more superior over the other derives the resource. The other one is excluded from the region by either decline in population, extinction or migration.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
