Energy Flow in an Ecosystem

Energy Flow in an Ecosystem. What is an Ecosystem?. An ecological system - consists of a living community and all of the physical aspects of its habitat - physical factors are known as abiotic factors and can include: light, temperature, precipitation, soil type,

Chapter 4 Pyramids and Productivity

Chapter 4 Pyramids and Productivity. Three types of pyramids:. Pyramid of energy flow Pyramid of biomass Pyramid of numbers. Pyramid of Energy Flow. Illustrates the greater cumulative loss of usable energy as energy flows through the various trophic levels

Productivity

Productivity. Energy flow through an ecosystem. ENERGY ENTERS THE ECOSYSTEM AS SUNLIGHT. Only 1-2% of the light energy falling on a tree is captured and turned into chemical energy by PHOTOSYNTHESIS The rest is reflected, or just warms up the tree as it is absorbed.

Energy Flow in Ecosystem

Energy Flow in Ecosystem. Sunlight! Producers , aka autotrophs use photosynthesis to create food. Produce ATP and NADPH to then form gluclose. Both producers and consumers use cellular respiration to gain energy from food.
