These penguins are all members of the species Aptenodytes patagonicus. What is the difference between a species and a population
Vikki [24]

Answer:

A species refers to the group of similar organisms that can interbreed to produce a viable offspring. For example, <em>Homo sapiens </em>is a species of humans, <em>Panthera leo </em>refers to the species of lions et cetera.

In contrast, a population in ecology refers to the group of organisms of the same species living in a particular area. For example, the deer population in a forest, human population in a town et cetera.

For example, <em>Aptenodytes patagonicus </em>refers to a species of penguins but number of penguins of the same species living in a particular area would make up a penguin population of that area.

Male cones grow near the of the plant while female cones are located near the
Rom4ik [11]

Male cones grow near the<u> lower region</u> of the plant, while female cones are located near the<u> top of the tree.</u>

Sexual Reproduction in Gymnosperms :

The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.
