which is a greater threat to a mountain ecosystem: a beetle that kills coniferous trees or a wolf thats hunts and eats deer?

Chemistry
1 answer:
Ipatiy [6.2K]3 years ago
6 0

Answer:

Explanation:

The mountain ecosystems are characterized by coniferous tree species such as pinus, firs, and spruces and species such as deers, bears, and wolves.

A beetle that kills coniferous trees would be a greater threat to the ecosystem than a wolf that hunts and eat deer because the dominant trees in the ecosystem are conifers. Hence, <u>a beetle that kills coniferous trees might end up killing the dominant tree species in the ecosystem and this will gravely affect other plant and animal species within the ecosystem. </u>

<em>Wolves and deers have their niche in the mountain ecosystem already and hence, their populations are naturally limited by limiting factors of the environment. Hence, a wolf that hunts and eats deers would be of a lesser threat to the mountain ecosystem.</em>

A saline solution contains 1.1% NaCl by mass. How much NaCl is present in 96.3 g of this solution
timurjin [86]

Answer:

= 1.0593 g

Explanation:

1.1% NaCl by mass, means;

1.1 g per 100 g = 0.011

Therefore; the amount of NaCl present in 93.6 g of the solution is;

= 0.011 × 96.3 g

What is the kinetic energy of a 25 kg object moving at a velocity of 2.5 m/s?
vovangra [49]

Answer:

<h2>78.13 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 25 \times  {2.5}^{2}  \\  = 12.5 \times 6.25 \\  = 78.125 \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>78.13 J</h3>
