Joseph Foster What is the biosphere? The biosphere is the global entirety of all ecosystems in ecology, which includes all life forms and their interactions with the elements of the atmosphere, hydrosphere, and lithosphere. Simply put, the biosphere is the area of the Earth’s surface where land, air, and water connect to sustain life. …
What is facilitated diffusion? Facilitated diffusion in a cell is a type of passive transport like osmosis. In this type of transport, molecules move from a high concentration region to a low concentration region with the help of a membrane protein. It is also a type of diffusion where there is a …
What is a biogeochemical cycle? A biogeochemical cycle is a pathway in ecology and Earth science by which a chemical substance is turned over or moves through the biosphere and Earth’s lithosphere, atmosphere, and hydrosphere. A biogeochemical cycle involves the exchanges of chemical elements between different parts of the Earth, such as …
What is the carbon cycle? The carbon cycle is the biogeochemical cycle in the study of ecology that circulates and exchanges carbon among the biosphere (the zone of life on earth), pedosphere (the outer surface layer of the Earth that is made up of soil and susceptible to soil formation processes), geosphere …
What Are Enzymes? Enzymes in a cell are simply biopolymers (large units derived from smaller units in living things) that catalyze biochemical reactions. The majority of enzymes are proteins with catalytic capabilities that are required to carry out various processes. A set of enzymes are required for life functions, especially in carrying out …
What is the water cycle? The water cycle, also termed the hydrological cycle, depicts the continuous movement of water within the Earth and its atmosphere in ecology. Definition of the water cycle The water cycle is the movement of water between the atmosphere and land. In more technical terms, the water cycle …
What is pollination? Pollination is simply defined as the transfer of a pollen grain (male gametophyte) to a flower’s stigma (receptive surface of the female reproductive organ), where it can germinate, grow through the style, and fertilize an ovule of a flower to produce seed. Every living organism, including plants, has the …
Active transport in cells is a necessary biological and genuine process that occurs in all biological systems, including plants, animals, and humans. This process is critical for maintaining life because it transports various essential materials in the eukaryotic cells, tissues, and organs. Water, hormones, gases, mineral nutrition, organic material, and other important …
