Which one is not needed ?
Answer:
Space
Explanation:
Answer:
Well... I would say it is gravity that is not needed.
Explanation:
In the picture at the top it says "we need to breathe air and live in some type of space. If these requirements are lacking, life ceases to exist."
Thus, stating that air, space, energy, and water are needed for life to exist. That leaves out gravity. Gravity is not needed for life to exist because, for example, humans and other living organisms are already living in outer space without the need for gravity.
Hope that helps!! :-)

Q 13. How will you describe the sequence of oxygen, carbon dioxide, anu
flow in your own words?
Answer:
Our body requires oxygen to complete it's all metabolic processes this demand of oxygen is fulfilled by oxygen carrier component present in the blood called Hemoglobin (HB). It binds with the oxygen that reaches from lungs to the heart, deoxygenated blood i.e. the blood that carries carbon dioxide with it, is converted into oxygenated blood and circulated throughout the body.This model of the cell cycle includes two arrows that each represent a process in the cycle. What do the two arrows represent?
what is carrying capacity? what type of population growth does it affect?
Carrying capacity is referred to a population size of species in a particular habitat. In an ecosystem, the population of a species will increase till it reaches its carrying capacity. Then the population size remains relatively equal.
What are the types of carrying capacity?Carrying capacity is the maximum limit till that the ecosystem can support the existence of the population.
There are four categories of carrying capacity, namely:
Physical.Ecological.Economic.Social.A specific environment's carrying capacity is the maximum population size that it can support.
The carrying capacity modifies the growth rate by slowing it when resources become scarce and stopping growth once it is reached.
Thus, it can be concluded that the carrying capacity is the average population size of species in a particular habitat which slows and stops the growth rate on reaching it.
