Answer:
If populations don't change very much over time, the ecosystem is in equilibrium .Populations decrease at higher levels of the food chain because they require more energy from other organisms.
The given question is seems it lacks some information, however, on the best knowledge of the provided information the correct answer would:
The change in the population of each organism is due to the evolution process that takes place because of changes in the environment in order to survive.
The changes in the genetic material of a particular population occur over a long period of time, the cause of this change is the process called evolution.
Evolution exhibits the adaptations that took place in organisms to their environmental changes that lead to altered genes, novel characteristics, and new species.changes in genetic variability and changes in allele frequencies over timenatural selection is the cause of evolution that occurs in organisms that are more likely to survive and reproducerandom fluctuations in allele frequencies in a population called genetic driftThus, the correct answer is - evolution.

how are bacterias different from animals ?
Answer:
Bacteria are neither animals nor plants.... Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or golgi apparatus.
Explanation:
Answer:
Bacterias have simple cells and are typically single cell organisms where as animals which have more complex cells are are multi celled organisms UwU

The larvae of potato beetles cover themselves in their own feces to avoid being consumed by predators. What system produces feces?
Answer:
Explanation below
Explanation:
Hemisphaerota cyanea, also known as the palmetto tortoise beetle, is a type of leaf beetle that cover themselves with their own feces, just to persuade most predators to pass them by. This form of outrageous defense, developed by the crafty beetle, was discovered by biologists at the Cornel university.
The feces comes out of the hindgut of the beetle, fashioned like golden strands, which can be used to protect the vulnerable body of the beetle.

What leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions?
A. less biodiversity
B.smaller food webs
C.greater biodiversity
D.specialist consumers
Answer: I think it’s C
Explanation: more biodiversity, the more reproduction and success.
Greater biodiversity leads to the likelihood that there are successful traits in an ecosystem. Therefore, option (C) is correct.
What is biodiversity?Biodiversity refers to the variety of species and the genetic diversity within those species that exist within an ecosystem. When an ecosystem has high levels of biodiversity, there is a greater chance that at least some species will have the traits necessary to survive and reproduce in changing conditions.
Organisms with successful traits in one set of conditions may not necessarily have those same traits in different conditions. Therefore, a diverse range of species with various sets of traits increases the likelihood that some of those traits will be beneficial in different conditions.

Describe the structure of the study independent variables , dependent variables and detail why the researchers would have used random allocation.
Answer:
To reduce systematic error.
Explanation:
The researchers would have used random allocation in order to decreases systematic error in the experiment. If we don't apply random allocation to the experiment, there is high chances of systematic error in the experiment and the result is not of high quality. Independent variables is a type of variable whose variation does not depend on another factor while on the other hand, dependent variables is a type of variable whose variation depend on another factor.

An animal with no natural enemy is a ____________.
Answer:
predator or a.pex predator
An animal with no natural enemy is an apex predator. Apex predators are also known as top predators or alpha predators.
They are species that reside at the highest level of the food chain within their ecosystems. They have no natural predators and primarily feed on other animals. Apex predators play a critical role in maintaining the balance and functioning of their respective ecosystems.
These predators are often characterized by their exceptional hunting skills, agility, strength, and ability to control the populations of their prey. They exert top-down control on the food chain by keeping the populations of lower-level consumers and herbivores in check, which in turn has cascading effects on the entire ecosystem. Thus, apex predators have no natural enemies.
