Identify three limiting factors that can prevent a population from increasing. Explain how each factor limits a population's size

Answers

Answer 1
Answer:

Answer:

natural disasters,emigration and scarcity of food

Explanation:natural disasters: this affect population where by organisms leave there area or habitat for another area due to unfavorable conditions eg. flood, bush fire, storms, earthquake etc. and can also lead to death.

Emigration:this is when organisms leave an area for another either in search of food, breeding purpose this reduses population where by organisms may never return.

scarcity of food:this occur when there is insufficiency or no food in an area which makes organisms leave their habitat for another in search of food and might even lead to death.

A flatworm obtains oxygen needed for cellular respiration through simple diffusion. A human obtains oxygen by breathing it in from the air and into the lungs. Which system is the flatworm missing?

Answers

Flatworms are high-flattened organisms dependent on direct diffusion as means of oxygen intake and release of carbon. This small organisms lack "fully evolved respiratory tissues such as lungs or gills and complex circulatory system as means to transport oxygen through out the body. 
>Direct diffusion of gases through the outer membranes can be used by organisms such as flatworms as a means of respiration due to their small size and simplicity.


Photosynthesis continues to increase with temperature.true
true within limits
not true

Answers

The answer is true. In Photosynthesis, the temperature continues to increase but with limits. In this process, plants and other organisms convert the light energy from the sun into a chemical energy then released to fuel the organisms’ activities. The rate of carbon assimilation increases as the temperature increases.

Final answer:

Photosynthesis increases with temperature up to a certain limit.

Explanation:

Photosynthesis is the process by which plants convert light energy into chemical energy to produce food. Temperature plays a crucial role in photosynthesis as it affects the enzymes involved in the process. In general, photosynthesis increases with temperature up to a certain limit, beyond which it starts to decline. This is because the enzymes become less efficient at higher temperatures.

It is the biological process by which green plants, algae, and some bacteria convert light energy, primarily from the sun, into chemical energy in the form of glucose and oxygen. This energy conversion occurs in chloroplasts, where chlorophyll pigments capture light and use it to convert carbon dioxide and water into sugars and oxygen, facilitating energy storage and supporting life on Earth.

how is nitrogen from the atmosphere, the aiotic part of the ecosystem, converted into the biotic part of the ecosystem n organisms

Answers

In the process of the nitrogen cycle.                 
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA.
