insect‘Exoskeletons are secreted from their epidermis and form three layers: inner, outer and upper epidermis. The epidermis is the topmost layer and is actually waterproof. … Because the exoskeleton is made of a carbohydrate called chitin, it actually stays moist on its own.

What is one way that both bacteria and fungi are important to the environment?

Fungi and bacteria are essential to many fundamental ecosystem processes.Certain types of fungi and bacteria can Breaks down fallen wood and litter, returning nutrients to the soil. Other types fix nitrogen in the soil and help plants get nutrients from the soil.

What is the process of genetic changes in two species due to long-term interactions called?

co-evolutionthe process of mutual evolutionary change that occurs when species pairs or groups of species interact.

What are the characteristics of organisms most likely to belong to the same species?

key point.According to the concept of biological species, living things belong to the same species If they could crossbreed to produce viable, fertile offspring. Species are separated from each other by pre- and post-zygotic barriers that prevent mating or the production of viable, fertile offspring.

How is nitrogen converted to ammonia?

Amination. When an organism excretes waste or dies, nitrogen in its tissues is in the form of organic nitrogen (eg amino acids, DNA). Various fungi and prokaryotes then break down the tissue and release inorganic nitrogen back into the ecosystem in the form of ammonia in a process called ammonification.

How long does nitrogen stay in the soil?

A water-soluble nitrogen source provides a rapid response within days or a week (depending on temperature), usually lasting approx. 2-6 weeks. Slow-release or controlled-release nitrogen sources can provide a longer nutrient period, lasting 8-12 weeks, and some even up to 20 weeks.

How do you explain natural selection?

Natural selection is The process by which populations of organisms adapt and change. Individuals in a population are naturally variable, which means they are all different in some way. This difference means that some people’s characteristics are better suited to the environment than others.

What causes branching in Cladogram?

What causes branching in Cladogram?Explanation: A new branch in the branch graph is given When new traits emerge that distinguish these organisms from the rest of the clade. Although organisms in a clade and their common ancestor share similar characteristics, each clade will have unique characteristics or traits.

What are the main disadvantages of natural selection?

Limitations of Variation The most obvious limitation of natural selection is May not have suitable changes. This may be because certain phenotypes cannot be established, ruled out by the laws of physics or the properties of biological materials.

Is natural selection a fact?

Explanation: The idea that organisms can evolve through micro and macro evolution is fact. . . the fact that natural selection occurs is a theory that natural selection causes changes that lead to the increased complexity required for a new Darwinian theory of evolution.
