Every living organism needs energy to survive, and since organisms cannot create energy, they have to either eat other organisms for energy or they have to make their own food. Plants make their own food through the process of photosynthesis, but this is not their only method of gaining energ...
Some bacteria help in nitrogen fixation, converting atmospheric nitrogen into a form that plants can use for growth and development. In the decomposition process, bacteria and fungi break down dead plants and animals, recycling nutrients back into the soil. This nutrient cycling is essential for ...
stems, and fruits. Animals eat the plants and convert the tissues into animal tissues. The cycle is completed when the animals die and their decaying tissues are eaten by soil organisms, a process that releases carbon dioxide.
Cells can be thought of as incredibly sophisticated robots that eat food, interact with the intercellular environment and build copies of themselves. The problem that researchers indevelopmental biologyfaceis to try to understand how cells can accomplish these feats. If we want to learn from the na...
thatEscherichia coliwas associated with the gastrointestinal tract of man and animals and that theE. coliassay was simpler to perform and more reliable at that time than the assay forSalmonella. It was believed that if water was contaminated with fecal matter thatE. coliwould be...
I’ve written for Asterisk before: What I won’t eat, on arriving at an equilibrium on the “it’s bad when animals suffer” vs. “but animal products taste good” challenge. This entry was posted in biology, history, metablogging, science on 2024, Oct 14. Recommendation: reports on ...
