Answer:

Biodiversity is defined as the variety of life forms existing on the planet and the number of species living within an area. The notion also covers the way diversity changes over time and moves from one location to another (“Facts on biodiversity,” n.d.). There is terrestrial and marine biodiversity that includes species living on Earth and in the sea. A number of species dwelling in a particular area helps to monitor the aspects of biodiversity. Maintaining biodiversity is important for people’s well-being since it plays a significant role in the contribution to human health and provision of raw materials. However, currently people often face the loss of biodiversity. Today this process is happening at a much faster pace than it did 50 years ago (“Facts on biodiversity,” n.d.). As a matter of fact, around 90 percent of all the fish on the planet was exploited within the last 50 years, a quarter of bird kinds were killed, and 70 percent of forests was destroyed. In addition, extinction threatens 18 percent of all mammals, 5 percent of the fish, and 8 percent of plants. Thus, it is possible to assume that the loss of biodiversity on Earth, which takes place nowadays, is directly linked to anthropological factors, including overhunting, overfishing, consumerism, and agricultural practices.

What type of reproduction do ferns use
Elena-2011 [213]

They both use a reproductive strategy called alternation of generations, where there are two different reproducing morphologies: a diploid sporophyte, and a haplod gametophyte. The sporophyte produces spores by meiosis (2N -> N), which disperse and form the gametophyte, which produces gametes by mitosis (N ->N). Two of those gametes fuse to create a diplod zygote (N + N -> 2N), which becomes the new sporophyte

There are differences between the two types of plants, especially the relative size of the sporophytes and gametophytes, but they both use this kind of reproductive strategy.

Living things grow and develop.how are these two features of life different?
Akimi4 [234]
Basically, when something grows it demonstrates an increment in something you can check. A tree can grow. That implies that it adds to its tallness. We can number the inches it has developed. An association can develop, adding individuals or different gatherings to itself. These are numbered effortlessly. Benefit can grow, including cash in diverse ways. Growth without anyone else's input, in any case, can't gauge advancement. If we take a gander at the stature of a man, it might be anything but difficult to accept they are a grown-up. When I was in evaluation school, a comrade of mine was more than six feet when he was only 11 years of age. If we take a gander at how tall he was, he would be viewed as a grown-up. Be that as it may, at that age, my comrade wasn't sufficiently created in his reasoning, not to mention passionate growth, to be viewed as a grown-up. There is an enormous difference. Without a waste of time, what is development? Development envelops numerous things however it is demonstrated by the subjective change of circumstances. This implies that as something adds to the nature of the entire makes strides. As a tree creates, it won't just develop, additionally have the capacity to replicate, like a natural product, be sound and proceed with growing. Hopefully, this clears up the most evident contrasts between the term development and growth and can direct you to a few assets that will help you toward better comprehension!
