Answer:
The population (of the bacteria) will reduce
Explanation:
This question appear a little confusing because of the structure of the second sentence. However, it appears to describe how an antibiotic works. Antibiotics work against bacteria by either making the environment toxic for the bacteria (which kills it) or inhibiting the growth/reproduction of the bacteria. Both patterns will eventually lead a sharp reduction in the population of the bacteria. Even if what the antibiotic does is to inhibit the reproduction of the bacteria, this act provides the body with an opportunity to fight the "unreproductive" remnants of bacteria thereby leading to the reduction of population of the bacteria.
1) Identify the problem
2) Design a solution or product
3) Implement the design
4) Evaluate the product/solution
First start with making observations, and decide on the problem. You want to generate ideas, look and decide your limits, then create a solution or product. Then, build your product/solution, and put it to the test. Did it work? Identify the pros and cons of your product/solution, and decide what you could do better to improve your design.
The correct answer is an ecosystem.
An ecosystem refers to the community comprising of living species and non-living constituents, like water, air, and mineral soil. The ecosystems involve associations among the species, and amongst the species and their surroundings.
In ecology, a community refers to an association or group of populations of two or more distinct species occupying the similar geographical region and in a specific time, also called biocoenosis.
