I believe this is Darwin's Theory of Evolution.
Hope this helps c:
Answer and explanation;
-Paramecium is an entire organism, and has to carry out all of life's function. A cheek cell is just an epithelial cell that doesn't have much because cheek cells are a part of a larger organism, therefore, they don't need to be mobile. Paramecium are free living , thus they need to be able to seek out food on their own.
-Organisms made of more than one cell are called multicellular organisms. The number of cells being less in smaller organisms does not, in any way, affect the functioning of the organisms. therefore a paramecium functions like any other living organism and has to attain activities such as nutrition and reproduction; etc.
The interactions between the atmosphere and the cryosphere are often complex.
The deposition of atmospheric impurities has been shown to impact the radiative properties of snow and ice, enhancing their melting.
They are both similar because they both replicate stuff and they are different because DNA replication is natural but DNA cloning is man-made.
hope it helps!

To understand food chains and food webs, we must start with where the energy begins. Sunlight is energy, and plants use this energy to turn water and carbon dioxide into plant food. This process is called “photosynthesis”. Plants also need minerals and nutrients. They get these from the soil when their roots take up water. While this might not sound like the kind of food you would want to eat, this plant food allows plants to grow, flower, and produceproduce things like acorns, potatoes, carrots, apples, pecans, and many other kinds of fruits.
Because plants make so much energy, they are called “producers”. Their ability to use sunlight to make food makes them a very important source of energy for other living things. Think about all the animals that eat plants. Wow, it's mind-boggling! Now, think about all the places that plants grow. From the oceans to the deserts to the mountaintops, plants can be found nearly everywhere basking in the sunlight and making their own food. And wherever plants grow, animals that depend upon them are sure to be found.
