There are tons of answers you could have.
One, for example:
Increased levels of CO2 decreases DO levels in the water and suffocates organisms, leading to population drops that can cause a genetic bottle neck effect, thus decreasing overall biodiversity. This could lead to extinction

Answer:
carries food produced by leaves
Explanation:
The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).

Answer:
The correct answer is desert.
Explanation:
If an entomologist wants to look for a good example of an organism that prevents water loss, he must look for organisms in the desert.
A desert is one of the ecosystems that <u>receives less water</u>, the rainwater that falls is<u> less than 150 mm per year.
</u>
Despite the heat and lack of water, there is a wide variety of living beings that inhabit this type of ecosystem. But for that <u>they must save water</u>, and they do this through adaptations that they developed when they were living in this place.
They can have two types of adaptations: physical or behavioral adaptations.
In behavioral adaptations, desert animals simply avoid the sun to generate greater water retention. Depending on the species, <u>some choose to go out only during the night</u>, and others <u>prefer to be under the shadow of a cactus.
</u>
Some species also get the water they need through the food they eat, which prevents them from having to go in search of water.
One type of physical adaptation is the one that occurs in those animals who accumulate fatty tissue in their body which allows them to <u>stay fresh and thus prevent water from evaporating.</u>
Answer- Skull and Ear Organs
Haikouella, a primitive early chordate fossil which is similar
in appearance to to lancelet, was found to have formed-brain, eyes, and
muscular segments. However it lacked two major things that
vertebrates have, namely skull and ear organs. Additionally, Haikouella<span> had
respiratory gills on its pharynx.</span>
