The invasive species are the species who are present in a non native ecosystem. The invasion of These species disturbs the environment of particular system by increasing the competition or destroying the vital component of the ecosystem.
The invasive species like brown tree snake exhaust the food of the other animals present in the ecosystem, as they are capable eating almost every type of food. Due to the presence of the brown tree snake, the competition for food increasing, which result in disappearance of many native species. Other invasive species can feed on the native species and cause decrease in their number, so, the invasive species disturb the ecological balance in the ecosystem.
The correct answer is skeletal development resulting in the movement of amphibians onto land and possibly evolved from lobe-finned fishes.
The initial lobe-finned fishes are bony fish with lobed, fleshy, paired fins that are connected with the body by a solitary bone. The fins of the lobe-finned fishes vary from those of all other fish in that each is borne on a lobe like, fleshy, scaly stalk protruding from the body.
This skeletal development will show that the species first developed in water and then gradually move onto the land and ultimately developed as species of land.
The principle fuel used as a petrol substitute for road transport vehicles is bioethanol. Bioethanol fuel is mainly produced by the sugar fermentation process, although it can also be manufactured by the chemical process of reacting ethylene with steam.
Basically, a plant can be considered as bioethanol becacuse it is a sugar fuel for animals. Animals consume plants for fuel to survive.
