What is the main difference between primary succession and secondary succession?

Answers

Answer:

Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.

Explanation:

Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.

Hope this helped!

Answer:

Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)

On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition

Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

Answers

Answer:

Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.

The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

(pls don’t guess or leave links)

Answers

Answer:I would say seeds, since it protects the bud of a flower and then the flower “hatches” from the seed and grows

Explanation:

The plant structure that is similar in functions to eggs is seeds. The correct option is C.

What are seeds?

A seed is an embryonic plant with a protective outer covering and a food reserve. The formation of the seed is a part of the reproduction process in seed plants, including gymnosperm and angiosperm plants.

Similarly, an egg is an oval or round object laid by a female bird, reptile, fish, or invertebrate that typically contains a developing embryo.

Bird eggs are protected by a chalky shell, whereas reptile eggs are protected by a leathery membrane.

Embryos are developing in seeds and eggs. Both provide food for the developing embryo. Both have protective coverings that keep them from drying out.

Thus, it can be concluded that the correct option is C.
