Question

How do humans depend on ecosystems?

Answer 1

Ecosystem:

1. Humans are greatly dependent on ecosystems to meet their needs and for their well-being.
2. Ecosystem service is the benefit we draw from an ecosystem.
3. Ecosystems provide us with food, clean water, and air, regulate diseases, pathogens, and climate change, support us with soil fertility, nutrient cycling, etc.
4. Venn diagrams are the diagrams that are used to represent the sets, the relation between the sets, and operations performed on them, in a pictorial way.
5. The Venn diagram, introduced by John Venn (1834-1883), uses circles (overlapping, intersecting, and non-intersecting), to denote the relationship between sets.
6. A Venn diagram is also called a set diagram or a logic diagram showing different set operations such as the intersection of sets, the union of sets, and the difference of sets. It is also used to depict subsets of a set.
7. For example, a set of natural numbers is a subset of whole numbers, which is a subset of integers.
8. The relation between the sets of natural numbers, whole numbers, and integers can be shown by the Venn diagram, where the set of integers is the universal set.
