Though they are small in structure, roots hairs have a very big job. Plants grow root hairs on the tips of their roots to increase surface area underground, which helps the plant absorb more water and nutrients.
That is why roots have a large number of root hair

Root hair cells. Plants absorb water from the soil by osmosis. ... Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

The book says energy "dissipates as heat" from an ecosystem or the biosphere. What does "dissipate" actually, physically mean?
Naddika [18.5K]

Dissipate actually means loss or disappearance of energy.

There is energy flow taking place in the ecosystem.In this energy flow,initially plants (producers/first tropic level) make use of solar energy for synthesizing food which is eaten by primary consumers(second tropic level).

During this consumption only ten percent of the total energy produced is transferred from one level to the next. Remaining energy is lost in the form of heat to the ecosystem due to certain metabolic processes occurring in the organism like respiration,growth etc.

Hence this loss of energy in the form of heat to the ecosystem is known as energy dissipation.
