Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate. [20]
Marine cyanobacteria include the smallest known photosynthetic organisms. The smallest of all, Prochlorococcus , is just 0.5 to 0.8 micrometres across. [ 44 ] In terms of numbers of individuals, Prochlorococcus is possibly the most plentiful genus on Earth: a single millilitre of surface seawater can contain 100,000 cells of this genus or more.
Biocrust influences a soil's microtopography, carbohydrate content, porosity, and hydrophobicity which are the major contributing factors to soil hydrology. The relationship between biocrust and soil hydrology is not fully understood by scientists. It is known that the biocrust does play a role in the absorption and retention of moisture in the ...
Fungi are abundant in soil, but bacteria are more abundant. Fungi are important in the soil as food sources for other, larger organisms, pathogens, beneficial symbiotic relationships with plants or other organisms and soil health. Fungi can be split into species based primarily on the size, shape and color of their reproductive spores, which ...
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
Soil Kit can be picked up for free at your Extension office, and the kit comes with a prepaid shipping label to mail in your soil sample. The cost of the SoilKit sample is $29.95 per sample.
Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. These organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as some reptiles (such as snakes ...
Simple Green has long appealed to consumers looking for a household cleaner that seems less hazardous than, say, Fantastik or Formula 409. And the manufacturer cultivates an image of an eco ...
