Explanation:
There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow.
Explanation:
The number of male gametes produced is way more than that of female gametes is because:
1. It will increase the probability of fertilization.
To make it clear: The sperm which is robust and can swim well gets the ovum. Multiple ova means multiple pregnancies. So nature dictates terms here and the woman rules to the roost.
2. More male gametes means the chances of variations inoccurring offsprings are higher.
(Note: I just improved an answer of someone else because this question was asked before)
Question: "Give reason why Number of male gametes produced is much more than the female gametes produced?"

Changes in maps of any kind are possible in the future. The probability of a change in a topographic map representation of a mountain in the future increases the further into the future we intend to predict.
Topographic maps are useful to obtain a general overview of the land in a certain area. Among the many things that these maps show the user are:
- Hills
- Ridges
- Valleys
- Lakes
- Rivers
- Creeks
- Trails
- Roads
- Elevation of the ground.
These contents can change based on natural occurrences. In the case of a mountain, natural disasters such as an <em>earthquake</em> or <em>volcanic eruption </em>can drastically change the topography of said mountain. The movement of tectonic plates is also a prime example of how the appearance of a mountain may change in the future.

In a eukaryotic cell, the ribosomes are found in the nucleus but since a prokaryotic cell doesn't have a nucleus, the ribosomes are floating freely in the cytoplasm. Hope this helped :)
Natural Selection is the process of those who have not evolved over time to be picked off by either predators or the environment. Evolution is the result of a species being altered in some way to adapt to their new environment to survive.
