The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __ 1 __ _. The

mamaluj [8]

Answer:

The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __autotrophos or producers_. The organisms that consume these are called _herbivores_ (it should end in -ores) which occur at the __second_ trophic level. The number of trophic levels that any ecological system will primarily dependent on the _consumer_ organisms.

Explanation:

In the trophic web occurs energy transference through organisms occupying different levels in the chain. Each level feeds on the preceding one and becomes food for the next one. The first link is occupied by autotroph organisms, which are the producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

Every link has an effect on the superior links and the immediately anterior link, meaning that whenever one of the links changes, the other ones will be affected.

Autotrophs or producers synthesize inorganic substances, such as light, and turn them into organic matter according to their own needs. These organisms are photoautotrophs, such as plants, or chemoautotrophs. They occur at the first trophic level.

Heterotrophs are those incapable of producing their own organic matter, so they feed on producers, depending on them to get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers. These animals can be herbivorous, carnivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.

In the particular case of herbivores, they occur at the second throphic level feeding on producers and being eaten by carnivores.

In general, most trophic chains are composed of 4 or 5 levels, depending on the number of consumers present, and the energy transference between levels.

Acetylcholine receptors on skeletal muscles are described as being ionotropic receptors because

DerKrebs [107]

Answer:

they are Na+, K+ and Ca2+ ion channels.

Explanation:

Ionotropic acetylcholine receptors are also called nicotinic acetylcholine receptors because beside acetylcholine (Ch) they respond to nicotine. These receptors are primary receptors in muscle for motor nerve-muscle communication that controls muscle contraction.

Two molecules of ACh are required for receptor to open. Since the receptors are linked to ion channels, the channels open. Opening of the channel allows positively charged ions to move across it: sodium enters the cell and potassium exits.

If the activation energy required for a chemical reaction were reduced, what would happen to the rate of the reaction?

Ratling [72]

The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.

Best Answer

Sediments can be deposited by wind or water but water moves most.
Loess is wind deposited particles. Alluvium is water deposited soil.
The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf.

Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits.

Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.
