A scientist studied a population of birds for 10 years. During that time, the population was never fewer than 30 birds and never

ahrayia [7]

Answer:

A particular population limiting factor or factors must have been removed

Explanation:

The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.

For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. <u>It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community. </u>

in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.

sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

Discharge is the volumetric rate of water flow past a point at a particular time.

Discharge = $\frac{volume of water}{time}$

We see that discharge is directly proportional to the volume of water in a stream.
It is inversely proportional to the time taken.
We know that volume is the amount of space occupied by a body. It is function of its size and shape.
A big water body that is deeper, wider and longer will have more wate and a greater discharge.
