Ecosystem

• Biotic components interact with one another through predation, competition, mutualism, commensalism, parasitism, and symbiosis.

• The chemistry of life
• Energy flow is the movement of energy from one trophic level to another.
• Matter cycling involves the recycling of nutrients within an ecosystem.
• Trophic levels are groups of organisms that occupy different positions in food chains or webs.
• Producers are autotrophs that convert solar energy into chemical energy using photosynthesis or chemosynthesis.
• Consumers obtain their energy by eating other organisms.
• Decomposers break down dead organic matter and recycle its elements back into the environment.
• Decomposers break down dead organic matter and recycle its components back into the environment.
• Decomposers break down dead organic matter, releasing nutrients back into the environment.
• Consumers obtain their energy by eating other organisms, either directly (primary consumers) or indirectly (secondary consumers).
• Food webs illustrate complex systems where multiple species interact as both predators and prey.
• Food chains show how energy flows through a simple system with only three trophic levels.
• The food chain shows how energy flows through an ecosystem from producers to consumers.
• Most energy is lost as heat during transfer between trophic levels.
• Energy flows through ecosystems from producers to consumers, with some energy being lost at each trophic level due to respiration and excretion.
• The flow of energy is unidirectional from one level to another.
• Food webs illustrate complex interactions among multiple species in an ecosystem.
• Food chains show the transfer of energy between species through feeding relationships.
• Energy flows through trophic levels, with producers at the bottom and decomposers at the top.
• The biomass pyramid shows how much living material there is at each trophic level, with producers having the highest biomass and decomposers having the lowest.
• Energy flows through food chains from producers to primary consumers, then secondary consumers, tertiary consumers, etc., with some energy being lost at each step due to respiration.
• Food chains show how energy is transferred between different trophic levels within an ecosystem.
• Food chains show how energy is transferred between species in an ecosystem.
• The amount of biomass (living material) decreases as one moves up the food chain.
• The pyramid of numbers shows how many individuals are present at different trophic levels in an ecosystem.
• Energy is transferred from one level to another in food chains, but not all energy is passed on.
• Energy flow diagrams illustrate the transfer of energy through an ecosystem at multiple trophic levels.
• Trophic level refers to the position of an organism within a food web based on what it eats.
• Energy is transferred between different trophic levels in an ecosystem.
• Trophic pyramids are used to represent the flow of energy between different trophic levels in an ecosystem.
• The pyramid of biomass shows the total mass of living material at each trophic level in an ecosystem.
• The amount of energy available at each trophic level decreases due to losses during respiration and excretion.
