How are changes in populations related to the availability of an ecosystem's resources?

a. population sizes are limited by the amount of resources that are available.

b. large populations need the same amount of resources as small populations.

c. changes in population are independent of the availability of an ecosystem's resources.

A. Population sizes are limited by the amount of resources that are available.

Explanation:

Think about it, the more people you have, the more food & water you need.

SO the answer is A.

(prove me wrong)

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it means there are 3 atoms of oxygen
