Answer:
D.
Explanation:
This is what being a producer means, making one's own food. A good way to remember this is, when you produce something, you make it.
Answer:
B. Stable ecosystems
Explanation:
The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.
A stable ecosystem is a sustainable one that does not change too much over the course of time.
Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.
- Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here.
- This suggests that the producers have enough energy to cater for their own need and that of the organisms there in.
- The consumers and decomposers have sufficient food available all year round.
- This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms.
- An unstable ecosystem cannot be biodiverse
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
Modeling of weathering and erosion can be performed in lab.
<h3>
Procedure of Modeling Weathering and Erosion using graham cracker:</h3>
1. Fill the ice cube tray or other tiny containers with 100 drops of water in each of the two or three cells using the eyedropper. Make the water entirely solid by freezing it for however long(for 3-4 hrs.).
2. Insert one graham cracker section into the bowl. To create a ramp-like structure out of the Graham Cracker, place one end on the bowl's lip and the other end at the bottom. To secure the cracker to the side of the bowl, dab some icing on the back of the cracker.
3.Add water to the eyedropper. Hold the dropper at a height of about 1 inch above the cracker's top. the dropper over the cracker in the middle. Apply 100 drips, always aiming for the same area.
4.Keep an eye on what the cracker does. Keep a record of your findings.
5. Pour the water into a glass that is clear after removing the Graham cracker. Make notes about the water, grading its cloudiness among your observations.
6.In the same manner as in step 2, clean and dry the bowl and add a Graham cracker to it. Grab an ice cube and wipe it over the graham cracker until it melts completely.
7.Remove the graham cracker and pour the melted water into the clear glass.
<h3>Result:</h3>
Appearance of water collected after is moved across graham cracker.

Answer:
Deltoid
Explanation:
The muscles of the trunk and the muscles of the lower extremity will be used for stability and moving the box across the 2 meters. The muscles of the upper extremity would be used to varying degrees to lift, hold, and lift the box to sternum level and place it in its place and which muscles contribute to the specific portion of the task you intend to study will depend on the magnitude of the load, the frequency the task is completed, the velocity at which the task is completed, the height differential between where the box is lifted from to the height at which the box is placed when the task is completed.
