Let's start off with an example. Imagine a population of organisms—let's say, deer—with access to a fixed, constant amount of food. When the population is small, the limited amount of food will be plenty for everyone. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. Because of the competition, some deer may die of starvation or fail to have offspring, decreasing the per capita—per individual—growth rate and causing population size to plateau or shrink.
In this scenario, competition for food is a density-dependent limiting factor. In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases. This is an example of negative feedback that limits population growth.

The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
<h3>
The lining of the air sacs in the lungs (alveoli) is comprised of what epithelium?</h3>
Simple squamous epithelium contain the air sacs or alveoli of the lungs. This kind of squamous epithelial cells are slightly porous which allows the oxygen from the air to enter the blood in the capillaries of the lung. So the squamous epithelium is the epithelium in which the lining of the air sacs or alveoli occurs. Each alveolus is lined by the squamous epithelium.
So we can conclude that: The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.

15. What's the requirement of every single natural process on Earth?
answer: Energy source
Answer:
The organisms reproduce in two ways:
Asexual Reproduction– In this process, only a single parent is involved and no gamete formation takes place.
Sexual Reproduction– In this process, two parents are involved and gamete formation takes place. Meiosis is an important step in sexual reproduction.
Key Points on How do organisms reproduce
- Reproduction is the process of producing new individuals of the same kind.
- Organisms reproduce in two ways- asexually and sexually.
- Asexual reproduction does not involve the fusion of male and female gametes. This takes place in bacteria, amoeba, hydra, etc.
- Sexual reproduction involves the fusion of male and female gametes and can be seen in humans and many animals.
- Fission, budding, vegetative propagation, fragmentation are some different types of asexual reproduction. It does not require any reproductive organs.
- Sexual reproduction involves the reproductive organs of male and female.
