The sun makes life possible. Without the sun, photosynthesis would not occur. Therefore nothing would grow. Eventually, plants would die off as well as animals eating those plants. Everything would basically slowly die off including the human race.
Rainfall is water released from clouds in the form of rain, hail or snow. It is the primary connection in the water cycle that provides atmospheric water delivery to the earth. Most precipitation falls as rain. When water reaches the soil, some of it is evaporated, while some rainwater soaks the soil (infiltration) as the soil is permeable, ie water can flow through it (runoff).
In the soil there are small pores, or voids, between the particles of sand, gravel and clay that make up the soil. Toward the surface, these pores may contain air and water. This is where plant roots will grow because plants need both water and air to survive. Rainwater that enters this upper soil can be sucked into the roots of a plant and later this water will be released back through the leaves of the plant in a process called evapotranspiration.
Haploid spores are released to form zygote, which grow into gametophytes.
The life cycle of the fern has 2 different stages :
(1) Sporophyte in which fern releases spores. (2) Gametophyte in which fern releases gametes. Sporophytes plants are diploid, Gametophyte plants are haploid and this type of life cycle is known as Alteration of Generation.
Haploid spore grows into a haploid gametophytes and then the gametophyte is fertilize and grow into a diploid sporophyte. Diploid sporophytes produces spores, completing the life cycle.
Sediment can come from soil erosion or from the breakdown of plants and animals. Wind, water and ice help remove these particles from rivers, lakes, and streams. The Environmental Protection Agency lists sediment as the most widespread pollutant in rivers, streams, lakes, and reservoirs. Wetlands are states where water is the primary factor controlling the environment and associated plant and animal life. They can be freshwater or estuarine (located at the coast with salty water) or both. The formation of sediment is a habit loss to these plant and animal life it mostly affects plants.
