Answer:
Ecology is the study of how organisms interact with one another and with their physical environment.
Explanation:
Answer:
Ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
calcium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for calcium is 1. There is large difference is present. That's why electron from calcium is transfer to the chlorine. calcium becomes positive and chlorine becomes negative ion.
There are two valance electrons in calcium so it needed to lose two valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus two electrons lost by one calcium atom are gained by two atoms of chlorine.
Ca + Cl₂ → CaCl₂
Answer:
It helps insure the survival of a species in a whole.
Explanation:
Allows different species, for example dolphins or meerkats, to mate and ensure survival in their habitats.
Answer:
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life.
Answer:
Migration.
Explanation:
When an individual leaves an area, they are migrating.
