Study Notes
Energy Pyramid
- Shows the flow of energy within an ecosystem
- Energy originates from the sun
- All life forms depend on the sun
- Ecosystem function relies on a interconnected web of life
- Energy is transferred through the ecosystem
Introduction
- Ecosystems function through a complex energy flow
- This involves all species, from tiny bugs to giant trees
- Every living being plays a role in energy flow
Sun's Energy
- Sun is the ultimate source of all energy within an ecosystem
- Energy from sun powers all living things in the ecosystem
- Energy flow from sun to plants, then to animals
- Energy is lost as heat along the transfer
Producers
- Plants are the base of the food chain
- All living things depend on plants as a food source
- Plants use sunlight, water, and air to make food through photosynthesis
- Producers make their own food to fuel the ecosystem
- Without producers, other life cannot survive
Consumers
- Consumers eat producers or other consumers to survive
- Consumers can't make their own food
- Three main types:
- Herbivores: eat only plants (e.g., rabbits, deer)
- Carnivores: eat other animals (e.g., foxes, lions)
- Omnivores: eat both plants and animals (e.g., humans, bears)
Consumers in the Energy Pyramid
- Energy is transferred between producers and consumers
- Much energy is lost as heat during transfer
- Levels of consumers:
- Primary consumers: eat producers
- Secondary consumers: eat primary consumers
- Tertiary consumers: eat secondary consumers
Decomposers
- Decomposers are the ecosystem's cleanup crew
- They break down dead plants and animals
- Animals and plants remain in simpler substances
- Important part of energy flow: release nutrients into the soil for plants to use again
- Without decomposers, dead matter would accumulate, disrupting the ecosystem
Energy Pyramid
- Energy is lost as it moves up the pyramid
- Amount of energy decreases at each level with primary producers having the most energy
- Primary producers have the greatest amount of energy, while tertiary consumers have the least amount
- Each level loses energy
- The top levels have less energy to survive
Summary
- Energy pyramid is a model depicting how energy moves through ecosystems
- Each level in the system is crucial for the ecosystem's balance
- The sun is the source of all energy flows in the ecosystem
