We can use a food chain to describe what the animals in an ecosystem eat. The arrows (→) in the food chain below mean 'is eaten by'. The giraffe is a herbivore – it only eats plants. The lion is a carnivore – it only eats meat.

Energy is crucial for events of every kind, in this world or any other. Without energy, nothing would ever happen. Nothing would move and there would be no life. The sun wouldn't shine, winds wouldn't blow, rivers wouldn't flow, trees wouldn't grow, birds wouldn't fly, and fish wouldn't swim; indeed no material object, living or dead, could even exist. In spite of all this, energy is seldom considered a part of what we call "nature." In The Energy of Nature, E. C. Pielou explores energy's role in nature—how and where it originates, what it does, and what becomes of it. Drawing on a wide range of scientific disciplines, from physics, chemistry, and biology to all the earth sciences, as well as on her own lifelong experience as a naturalist, Pielou opens our eyes to the myriad ways energy and its transfer affect the earth and its inhabitants. Along the way we learn how energy is delivered to the earth from the sun; how it causes weather, winds, and tides; how it shapes the earth through mountain building and erosion; how it is captured and used by living things; how it is stored in chemical bonds; how nuclear energy is released; how it heats the unseen depths of the planet and is explosively revealed in the turmoil of earthquakes and volcanoes; how energy manifests itself in magnetism and electromagnetic waves; how we harness it to fuel human societies; and much more. Filled with fascinating information and and helpful illustrations (hand drawn by the author), The Energy of Nature is fun, readable, and instructive. Science buffs of all ages will be delighted. “A luminous, inquiring, and thoughtful exploration of Earth’s energetics.”—Jocylyn McDowell, Discovery

Biomonitoring of water quality is very much essential for assessing the overall health of water bodies and safe supply of drinking water. The chemical nature of toxicant is highly dynamic in environment with time and space whereas biological system can integrate all environmental variables over a large period of time in terms of effect that can be easily measured and quantified. In view of the above, there is a pressing need to determine the water quality of natural resources as well as drinking water based on the standard protocols and guidelines from regulatory agencies. It is clear that the synthetic chemicals are essential for our society to maintain the health and well being of the people. However, there has been a range of detrimental effects on human health and natural environment. In general, we need to improve our management of waste chemicals discharged into the air, water and soil environments. New techniques are needed to predict adverse effects before they occur and for the treatment of wastes. In addition, a range of social, political and economic factors will be needed to be taken into account in order to achieve success.

Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems.In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book:provides a snapshot of the past health of the North Atlantic and compares it to its present statuspresents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic levelconsiders the factors that have led to the current situationdescribes the policy options available for halting the declineoffers recommendations for restoring the North AtlanticAn original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems.This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
