Which of the following is not an invasive species?
1 Parthenium hysterophorus
2 Neumbo (lotus)
3 Lantana camara
4 Eichhornia crassipes
Explanation:
Invasive species are non-native organisms that may get incorporated into a foreign ecosystem and compete for habitat, food, etc with the native species, many a times threatening the existence of the native species. Lantana is native to tropical regions of America and Africa. Parthenium was introduced in India as a contaminant with wheat. Eichhornia was introduced for its beautiful leaves and flowers from South America, which has now become a weed covering the entire surface of the water body and preventing the growth and development of organisms below. Nelumbo (lotus) is not an invasive species.

Bacteria and fungi developing on dead decaying organisms are $\qquad$
1 Symbionts
2 Saprophytes
3 Parasites
4 Commensals
Explanation:
The fungi and the bacteria feed on the dead and decaying matter and are known as saprophytes they are also known as decomposers. Saprophytes are fungi and several types of bacteria. An autotrophy is an organism that uses light water carbon dioxide or other substances to create its own food.

Western Ghats have a large number of plants and animal species that are not found anywhere else. Which of the following term is used to notify such species?
1 Threatened species
2 Keystone species
3 Endemic species
4 Vulnerable species
Explanation:
Western Ghats have a large number of plants and animal species that are not found anywhere else. The term is used to notify such species endemic species. The total area of the western ghats is 140000 square $\mathrm{Km}$. it is a part of the state of Karnataka Tamil nadu, Kerala, Gujarat. The largest number of endemic plant species are found here.

Two butterfly species are competing for the same nectar of a flower in a garden. To survive and coexist together, they may avoid competition in the same garden by:
1 feeding at the same time
2 choosing different foraging patterns
3 increasing time spent on attacking each other
4 predating on each other
Explanation:
If two specifies compete for the same resource, they could avoid competition by choosing defend foraging pattern. Mac Arthur showed that five closely related species of warblers living on the same tree were able to avoid competition and co-exist due to behavioral differences in their foraging activities.
