Answer:
Only one species can fill an ecological niche because each niche is destined exclusively for each species, since its structure, physiology and behavior determine it.
Explanation:
An ecological niche is the way in which each species relates to its environment, to other species and takes advantage of the resources available for its development, being an exclusive and individual characteristic of that species.
The ecological niche is a concept that many consider abstract, since it is unique for a species. Each species has a physical structure, functioning and behavior that differentiates it from the others, which leads it to occupy a certain place within an ecosystem, which would be its ecological niche.

Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer: <u>Option B; It traps light energy and converts it into chemical energy.
</u>
This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.
This pigment is present only in plants, so option A is incorrect.
This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.
Answer:
1440
Explanation:
Members except president, secretary and joint secretary = 9−3=6
Their arrangement = 6!
No. of arrangements of secretary and joint secretary at wto places
