Sunlight and h20 and co2 are present
One way that they are economically valuable is that it is mostly made up of the stuff that we have and need now like papers, tables, money, houses, etc. Wood is very very important in the human society and the place to get them is the forests.
A way that it is ecologically valuable is that the trees create habitats for the animals that live in the forests for protection from storms, other animals, etc. The trees in the forest can also be a source of food for some animals because those animal can feed on the leaves.
Answer:
Both
Explanation:
Depends on what happened in that video. I would rewatch it and write about what the video said about flooding and relate it to the river. Could be an ice jam or something else slowing the flow of water suddenly opened up. A breaking dam? Flash floods from an abundance of rain. As the amount of water in the river increases, so does the flow rate. If the amount of water suddenly increases more than the river was used to/it could hold, it will flood.
Rewatch the video and see if this relates at all :)
Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.
