Answer:
Earliest- gametophyte dominance, sporophyte dependence
Middle- sporophyte dominance, gametophyte independence
Recent- sporophyte dominance, gametophyte dependence
Explanation:
The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores. The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.
In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
Biotic Factors depend/rely on abiotic factors because living things (biotic) need nonliving things (abiotic) to survive. Biotic rely on other Biotic factors because they need the food and resources from other living things.
For example, we (biotic factors) need energy from the sun and oxygen/air ,which is abiotic factors, to live and grow. Just like plants (biotic) need the sun's energy (abiotic) to help it grow.
I hope u understand me. Sorry If u don't
Because of its ability to form large complex and diverse molecules
Answer:ATP
Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups. The word adenosine refers to the adenine plus the ribose sugar.
