Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings, so that the state ..

. Here again some of the energy is released as heat. When primary consumers are eaten by secondary consumers, the same process is repeated at every step of the food chain. Here it must be remembered, that energy released as heat is considered as energy lost. We can thus conclude the following: Conv..

Energy flow
Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy is transferred to them. Carn..
Tracheids
Tracheids are elongated dead cells that have sloping end walls. The cavity is empty as the cells are dead. The walls are thickened with a material called lignin. These thickenings are in different patterns. The cells are arranged end to end. Vessels are also dead cells that have variously patt..Water
About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour and this forms the hydrosphere. The main component of hydrosphere is water. ..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
very patient tutor, explained everything step by step did not loose patience when i was not understanding and did not give up till i understood, 5 star i give coz she rocks.Highly recommend Tutor Vista
Tutor is by far the most enjoyable, fun, and academically enthusiastic . It was a pleasure working with him- amanda
