A food web is the entirety of interrelated food chains in any and every ecosystem. This delicate balance is the connection between predator and prey‚ consumer and producer‚ and autotroph and heterotrophs. Food web’s also allows you to follow the direction of the flow of energy as each organism consumes each of their indicated food sources. For example‚ the energy from the sun is taken in by producers‚ such as ‚ trees‚ grass and fruit. Then goes to an autotroph would be eaten by a second trophic

Chapter 9: Ecosystem Approach Variation of Forests in Their Age‚ Makeup‚ and Origins A. 2 Major Types of Natural Forests 1. Old-growth/ Primary -uncut/ regenerated forest that has not been seriously disturbed by human activities/ natural disasters for 200 years or more - reservoirs of biodiversity (provide ecological niches for a variety of wildlife species) 2. Second- growth - stand of trees resulting from secondary ecological succession B. Tree Plantation/ Tree Farm/ Commercial Forest

Ecosystem Preservation versus Conservation Earth is composed of many different ecosystems and each one is a "dynamic complex of plant‚ animal‚ and micro-organism communities interacting with the non-living environment as a functional unit" (Protecting Threatened Ecosystems‚ 2004). These ecosystems are an intricate part of the human lifecycle as they provide us with our water‚ food and energy. Since mankind is in a take and take some more relationship with the ecosystems‚ many of them have had their

this project because in previous years and class we were just well known about the term “ecosystem” but now as we have done this project we have now learned various things about ecosystem in depth and that will help us in our course study in coming days. This project is based on term “ecosystem” and “Food chain” after going through it many will be able to answer these questions: * What is an ecosystem‚ and how can we study one? * Is the earth an open or closed system with respect to energy

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

BEECH FOREST ECOSYSTEMS INTRODUCTION This essay will look at beech forest ecosystems‚ describing the main characteristics‚ along with pre-human and current distribution of beech forests. Vegetation structure and native fauna associated with the ecosystem will be looked at with examples of species given. Environmental effects such as altitude‚ latitude‚ rainfall and soil drainage‚ and how they can affect beech forests will be investigated. Anthropogenic effects will also be looked at‚ explaining

Pollution and Its Effects on Ecosystems By Malik Lockett 808 Pollutions of ecosystems can harm living organisms. It can cause death‚ the worst experience ever. Let’s learn about. A pollution is the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects. The main country that is experiencing pollution is Mexico. In Mexico City there is air pollution caused by smoke
