For a project I needed to ask 25 people : do you think eating meat is bad for the environment?
Lelu [443]

Answer:

Yes (It's more inefficient)

Explanation:

in ecology there are things called primary producers (plants) that are eaten by primary consumers (cows and chickens) and then there are humans, secondary consumers, that eat cows and chickens for energy.

The further we move from eating primary producers the more inefficient we become in consuming energy. Meaning, it requires a lot more natural energy consumption to support a human that lives on meat only as compared to a human that eats plants only. this inefficiency only magnifies when communities practice unsustainable food methods.

There are sustainable ways to eat meat, but (at least in the US) our current conventions of meat production are unsustainable and environmentally destructive.

5. What is the difference between mitochondria and chloroplast?
FinnZ [79.3K]

Answer:

C. Mitochondria convert sugars into energy, while chloroplasts carry out

photosynthesis.

Explanation:

Chloroplasts have the ability to use light to convert carbon, derived from carbon dioxide into sugar. Mitochondria on their part break down simple sugars into carbon dioxide and release energy. Chloroplasts are larger and have greater complexity than mitochondria, and they have several critical functions to perform, besides the generation of ATP. Apart from converting carbon dioxide to carbohydrates they synthesize amino acids, fatty acids, and the lipid contained in their own membranes.

Mitochondria are to be found in both plant and animal cells, whereas chloroplasts are found only in plant cells. The former have a structure composed of a prokaryotic cell, whereas Chlorplasts are made up of stacks of thylakoids surrounded by a fluid called stroma. According to some theories, mitochondria exist because of endocytosis of aerobic bacteria, while chloroplasts are around because of the result of endocytosis of photosynthetic bacteria.

Chloroplasts exist only in plant cells and lend the green color of most plants. Mitochondria on the other hand are found in both animal and plant cells and are engaged in the production of ATP. To use simple layman language, mitochondria in animal cells changes energy into forms that animals can use, while chloroplasts in plant cells convert sunlight into energy that plants can use. From this it follows that mitochondria in a sense are the power plant in the animal cells, because it generates energy. Chloroplasts provide the green color to the plant due to the chlorophyll present in them.

Mitochondria cells are 1 to 10 um long in length. These can change shapes, get around, and divide into two. The cell is surrounded by an envelope of two membranes. The membrane on the outside is smooth while the other one is marked by what are called cristae.

Photosynthesis happens only in plants. This is because only plants contain chloroplasts. Thus we can see that mitochondria and chloroplasts are the building blocks of life for plants and animals respectively in the sense that they provide nourishment to the organisms. The two are also representative of the dividing line between the two kingdoms of life on earth-the animal and the plant.

These two structures are markers of two philosophies of life form if one may use the use the term. One that is self sustaining, manufacturing its own food, the other that is dependent upon the former as the primary source of food, but far more complex and evolved way of life in many other aspects.
