Tropical rainforest, temperate deciduous forest, and boreal forest (also called the taiga)

lorasvet [3.4K]

<span>Characteristics that mentioned biomes have in common are:
- They are all forests, dominated by trees and other woody vegetation.
- They inhabit animal life with great microbial diversity.
- They all have big carbon sinks.

Still, trees different in a number of ways in these three biomes:
- </span><span>Tropical rainforest: Trees are evergreen and have large green leaves. Canopy is multilayered and dense, so there is a little light in the forests.
- </span><span>Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- </span><span>Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.</span>

Cultures of a bacterial species were incubated on the shelf of a refrigerator (5 C), out on a lab bench top (22 C), on the shelf

Setler79 [48]

D) Psychrotrophs.

Explanation:

Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
Halophiles prefer high salt concentration.
Mesophiles prefer temperatures with a average of 37 degree Celsius.
Anaerobes grow in absence of oxygen.
In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.

Saprophytes are fungi that feed on dead and decomposing organisms

UNO [17]

Saprophytes are fungi that feed on dead and decomposing organisms they secrete enzymes that digest additives of cell walls, including cellulose and lignin.

<h3>Why are fungi called as the saprophytes?</h3>

Fungi purpose decay through liberating enzymes onto the lifeless animal or plant. These smash down complicated compounds into easy soluble ones that may be absorbed through decomposers. Organisms that feed on lifeless on this manner are referred to as saprophytes.

Saprophytes are residing organisms that stay and feed at the stays of different organisms i.e on lifeless and decaying organisms. Saprophytes, additionally called saprotrophs. They are immensely crucial for soil biology.
