Answer:
Paramecium- 0 days/ 50 paramecium
5 days/400 paramecium
10 days/ 900 paramecium
15 days/ 860 paramecium
Bear- 0 days/ 2 bears
20 years/ 26 bears
40 years/ 230 bears
60 years/ 250 bears
80 years/ 248 bears
100 years/ 252 bears
Explanation:
The population of the paramecium will keep on increasing until an equilibrium is reached. The resources will become limited and hence, the paramecium will start competition for the limited resources. As a result, the population of the paramecium will decline rapidly after equilibrium.
The growth rate of bear is very less as compared to that of paramecium growth rate. Along with the growth rate, there are other factors which will be responsible for its numbers such as resources, hunters etc. Also, it uses sexual method of reproduction hence the growth rate will not be like the paramecium growth rate.
Answer:
Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.
Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.
while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.
Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.
Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.
Foreign invaders have proteins called antigen, which antibodies lock onto to neutralize. The foreign proteins are different from proteins in our own body, so the immune system can recognize them and finally eliminate them.

Hope this helps! (please mark as brainiest!)
The first known single-celled organisms appeared on Earth about 3.5 billion years ago, roughly a billion years after Earth formed. More complex forms of life took longer to evolve, with the first multicellular animals not appearing until about 600 million years ago.
