Answer:
А. They belong to the same group of the periodic table.
Explanation:
Two elements possess similar chemical properties if they belong to the same group on the periodic table.
What determines the chemical properties of elements;
→ the number of valence electrons an element contains determines its chemical properties.
- On the periodic table, groups are vertical arrangement of elements.
- Periodic groups classifies elements into groups based on the number of valence electrons they contain.
- So, elements in the same group will have the same number of valence electrons and hence similar chemical properties.
All of the consumers would be affected, and be forced to adapt. Since the amount of grass has decreased, the primary consumer would struggle to survive, and most likely, die out. Since the primary consumer has probably died out, the secondary would either die, or be forced to adapt to the situation, or change habitats ( applies to the rest in the food chain / web).
