Because the way our solar system works it only happens either yearly or just depends on the situations
Predators are the keystone species because they limit the population of prey.
<h3><u>Explanation:</u></h3>
Predators are those species which hunt for other animals to consume them as food and live. Where prey are those animals who are being hunted and killed by predators.
Keystone species are those species whose absence or removal from a ecosystem will greatly reduce the diversity from the ecosystem to a huge extent.
Now, if a predator like lion is eliminated from the ecosystem, then the prey like deer, goats etc in the ecosystem will live and reproduce at a very high rate, which will greatly increase the population density of these species. So the food for them will be killed at a very high rate, decreasing the plant varieties and population. So the overall diversity in the ecosystem will be highly reduced.
So the predators like lions, tigers, etc are the keystone species of an ecosystem.

<span>Within eukaryotic cells, there is a network of organelles which have unique functions.
An organelle is termed as a specialized subunit within a cell which has specific functions and their functions are very vital for a cell to live. Organelles can be identified by microscopy and purified by cell fractionation.
In eukaryotic cells has many types of organelles. Larger organelles which are found in eukaryotic cells are visible with the light microscope, for example, vacuole and nucleus.
Some of the major eukaryotic organelles include plastid, endoplasmic reticulum, flagellum, mitochondrion, vacuole, nucleus and Golgi apparatus</span>
Answer:
they are the place where cell respiration takes place
Explanation:
Cellular respiration is a series of metabolic reactions used by the cell to create energy (ATP), these reactions occur partially in the cytoplasm, but mostly in the mitochondria. On the other hand, vacuoles store water in plants and help give them structure, are the largest organelle in plant cells, and both plants and animals have them. Therefore the answer is, they are the place where cell respiration takes place.
