The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.

Considering the data in the question, the focal length of the objective lens that will give a total magnification of 200x is <u>0.8cm focal length.</u>
The whole question is:
You are using a microscope with a 10x eyepiece. What focal length of the objective lens will give a total magnification of 200x? Assume a length L = 160mm.
<h3>How was the answer derived?</h3>
Given that total magnification is 200
And the Assume length is 160
Since we used a microscope with a 10x eyepiece, the magnification would be divided by 10.
=> 200 ÷ 10 = 20.
Also, the focal length is measured in centimeters or meters; we would change the millimeters of focal length to centimeters. Therefore, we have 160 ÷ 10 = 16
The formula for the focal length of the objective lens = assumed length ÷ total magnification.
=> 16 ÷ 20 = 0.8cm.
Hence, in this case, it is concluded that the correct answer is "0.8cm."

The difference in muscularity between the crop and the gizzard earthworm is that; Crop muscularity is soft while for gizzard it is hard.
<h3>What are the differences in Muscularity?</h3>
Earthworms usually eats the soil that has organic matter such as leaves and others.
Now, the digestive system of earthworms is made up of pharynx, oesophagus, intestine, gizzard and crop. The mode of digestion is that the food passes through the esophagus after which it is now pushed down the crop where it is used for storage and then in the gizzard where the food is being grind.
Finally. the difference between the crop and the gizzard is that the crop muscularity is soft while that of gizzard is hard.
