Answer:
True
Explanation:
The plasma membrane does not allow the charged and polar substances to cross through its inner core that is made up of non-polar fatty acid tails of the phospholipids. Therefore, membrane proteins serve as transport proteins. Some of the transport proteins allow the movement of substances down the concentration gradient without any energy input. This passive movement of substances via membrane transport proteins is called facilitated diffusion.
Carriers and channels are the membrane proteins that facilitate the diffusion of substances. Carrier proteins pick the substances from one side of the membrane and undergo a change in shape to deliver the substance on the other side. Channel proteins make a passage for the movement of substances. Examples: aquaporins, ion channels.
Explanation:
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly

Species diversity hurts ecological succession. Explanation: Species diversity does not contribute for ecological succession. The diversity among the species is high at pioneer community. However as time passed competition and interaction causes a significant drop in species diversity.
Answer:photosynthesis involved the process of energy build -up from monomers like carbon iv oxide and water (anabolism) with the help of solar energy while cellular respiration involved the breakdown of energy in the form of ATP with the help of oxygen (catabolism) into carbon iv oxide and water as waste products.
