There are different levels of organization in living systems, from molecules like DNA (genes) to the entire biosphere. When it comes to biology levels of organization they start from: genes → cell → organ → organism → species population → community → ecosystem → biome → biosphere Living beings are extremely organized and structured, following …
The primary producers are blue-green algae, zooxanthelle, phytoplankton, seagrass, and brown algae. The primary consumers are zooplankton, corals, sponges, Atlantic blue tang, and queen conch. The intermediate consumers are the sergeant major, flaming tongue snail, bar jack, grouper, Caribbean lobster, bicolor damselfish, polychaete worm, cushion sea star, and southern stingray. The top predator in the coral reef food …
Sometimes science seems like something that takes place in a laboratory away from everyday life. It may be, but the impact of ‘s scientific research is having a tremendous impact on your daily life, from the food you eat the energy that powers your home. Here are some of the ways that biology affects your …
What Is A Cell Biology? Cell biology is the examination of cellular structure and function and revolves around the concept that the cell is the basic unit of life. In the 1830s, two scientists, Schleiden, who studied plant cells and Schwann, who first studied animal cells, provided, the first clearly established definition of cell is …
Charles Darwin is most remembered today for his contribution to the theory of evolution through natural selection. The seeds of this theory were sown in Darwin’s mind through observations made during a five-year voyage across the New World on a ship called the Beagle. There he studied fossils and geological records, the geographical distribution of …
Not all scientists agree on what life is all about. There are several features that describe most living things. However, for most of the features listed below, we can think of one or more examples that might break the rule by classifying something that doesn’t live as alive or something that lives as non-living. Hence, …
In addition to the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall that surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress, and also allows cells to develop turgor pressure, which is the pressure of the …
Natural selection is the maintenance of a functional advantage that enables a species to compete better in the wild. Natural selection is the naturalistic equivalent of backyard breeding. Over the centuries, human breeders have dramatically changed the pet population by choosing individuals and removing unwanted properties over time. Similarly, natural selection gradually eliminates the species …
