Answer:
Explanation:
Base on my understanding of your question, it seems you are comparing susceptibility of disruption of ecosystems with fewer organizations to that of numerous organizations.
Let start from the definition of an ecosystem which can be defined as community of living organisms such plants, animals and non living organisms components in the same environment cohabiting to form a system and are linked together through nutrients and energy cycles. In other word, we can say no organisms exist in isolation and as such they are depend on each others. We also have different type of organisms in an ecosystem which are character as consumer; those that predate on others for their surviver which are known as heterotroph, while some are capable of producing their own food and are termed autotroph either through photosynthesis or chemosynthesis. Some organismsalso feeds on dead things and they are termed Scavengers or detritivores.
So, going by these explanations, ecosystem with few organizations will be more susceptible to disruption because some organisms will go into extinction as they are being eaten up by heterotroph organism and as such themselves will not survived as their will no food for them to feed on again. As such, the cycle will not complete leading to break in nutrients and energy cycles and eventually the ecosystem will be disrupted. While those with many organizations, the cycles continued as the food chain continues and the ecosystem continue to exist.
The stomata and their guard cells allows this happen.
Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.
Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.
In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.
C: primary Consumer
<em>primary consumers</em> are typically animals that eat plants aka herbivores.
<em>producers </em>would be plants
<em>secondary consumers </em>are typically ones that eat meat or eat meat and plants aka omnivores.
<em>decomposers, </em>I believe are like your fungus or anything that feeds off of dead organisms or eat the waste of that organism.
Hopefully this helped. I remember learning about this in college.
I think the correct answer from the choices listed above is option D. Modern fishing practices threaten biodiversity mainly through the removal of community food supplies. When people remove a significant amount of fish, portions of the food web are disturbed and can affect a certain ecosystem.
Adenine, Thymine, Cytosine & Guanine
