Answer:
a move from the fundamental niche to the realized niche for both species.
Explanation:
The niche of an organism is the functional role of the organism in the community or the ecosystem as a whole. This include the environment an organism lives and all the jobs it does in it.
Fundamental niche refers to all the possible functional roles of an organism in an ecosystem while realized niche refers to the specific roles the organism is limited to as a result of resource limitation, competition or other factors.
Resource partitioning involves the division of limited resources among organisms so as to avoid competition within the niche.
<em>Hence, resource partitioning causes a move from the fundamental niche of an organism to the realized niche of that organism. </em>
Within a gymnosperm megasporangium, the following developmental sequences that are correct, assuming fertilization occurs is: megaspore, female gametophyte, egg cell, sporophyte embryo. The last Option (Option D) is correct.
In gymnosperm megasporangium, the meiotic division produces four haploid megaspores from a single cell, three of which generally degenerate. The female gametophyte is formed by mitosis from the surviving megaspore.
Prior to fertilization, the male mature gametophyte needs to be transferred to the female gametophyte for fertilization to take place.
When the nuclei of the sperm encounter the nucleus of the egg cell in gymnosperms, it fuses with the egg nucleus to produce a diploid zygote.
Mitosis occurs in the fertilized egg to initiate the growth of a new sporophyte generation (the multicellular embryo of the seed.)
Therefore, we can conclude that we've understood the mechanism of developmental sequence in the gymnosperm megasporangium.
