Yes. <em>You</em> do.  Try thinking about it in reverse:

One obvious form of mechanical energy in an organism is the energy
that you have in you to make your muscles work, to move you around,
to throw a ball, to pick stuff up, etc.y

Where does the energy come from to make your muscles work ?
It comes from the food you eat.

Where does the energy in the food you eat come from ?
It comes either from the plants you eat, or else from the plants that
the animals you eat eat.  (Or possibly from the plants eaten by an
animal before that animal is eaten by an animal that you eat.)

Where does the energy come from that's stored in the plants ?
It comes from the sun.

So there. You've traced the path backward, from the mechanical energy
in the organism, back to the sun.  Can you turn it around now, and trace
it forward ?

Light energy (sun)(by photosynthesis)---> plants(stored in fruits stem and other parts)---> consumed by herbivores and omnivores(these are inturn the prey of carnivores)--->all these animals release energy by oxidising glucose from plants(this energy is used by animals to move their muscles, locomote etc. that is, the energy from sun is converted to mechanical energy)

How are currents in the Pacific Ocean affected by El Niño?
mylen [45]

The answer is; Warm water moves to the east instead of to the west


Normally, when the waters in the Pacific warm up, the prevailing winds that blow from east to west drag the warm surface currents westwards and upwelling of cold currents occur at the west coast of South America. However, in El Nino, the Pacific ocean waters heat more than usual. The prevailing winds weaken and begin to blow predominantly towards the east. The warm currents are therefore dragged to the east and cause torrential rains in Western coast South Americas.

1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Des
nasty-shy [4]

Answer:

Examples:

- Short-term adaptation: feedback inhibition

- Long-term adaptation: regulation of gene expression

Explanation:

Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
