Answer:
Biodiversity is usually defined as the diversification of living species that exist on earth and the complexities that occurs in the ecosystem. It includes all the plants, animals, humans and micro-organisms.
The biodiversity is often affected by factors such as climate change, loss of habitat area, and occurrence of invasive species.
Three of the biological services that are provided by biodiversity are as follows-
- A large number of medicines are being made from the various plant species that exist in an ecosystem.
- It provides food, on which the organisms are dependent on it.
- It also provides materials that are used for construction purpose and used as shelter.
A vector is a
quantity that has both magnitude and direction and to identify the components
of vector, you need to break it into parts called components. These components depict
the influence of that vector in a given direction. For example, in the vector
(6, 2), the horizontal or x-axis component is 6 and the vertical or y-axis
component is 2. With this, you have an angle and a magnitude to define a
vector, where you have to find the components yourself with the help of
trigonometry. The magnitude of vector is expressed as v and by multiplying both
sides of these equations by v, you can expressed the x and y components as Vx = vcos and Vy = vsin.
The combined
influence of the two components is equivalent to the influence of the single
two-dimensional vector and this single two-dimensional vector could be replaced
by the two components.
Answer: This is called allopatric speciation. The species continue to evolve in the own way, adapting to their different conditions. The eventually become two different species adapted to each environment.
