Early pre-cambrian period the atmosphere consisted only of nitrogen and carbon dioxide without oxygen.
<span>A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
</span><span>Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.</span>
Answer:
We could use up all of them right away and not have the resources for humans and animals to survive.
Explanation:
Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.
Hope this helps!
Convert carbon dioxide gas to oxygen gas.
produce the food the plant needs to grow.
However, some folks have missed the purpose of photosynthesis. It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
Answer:
Explanation:
I am the thing that goes bump in the night. The shadow-like figure all are too afraid to identify in their room. The silent stalker of your waking nightmares and lucid dreams.
