Lesson 2: Energy Flow in Ecosystems Flashcards
the ability to do work or heat objects. In Thermodynamics,
this is neither created nor destroyed
energy
7 types of energy
electrical energy
mechanical energy
chemical energy
gravitational energy
radiant energy
nuclear energy
magnetic energy
2 major classifications of energy
potential energy
kinetic energy
energy that is not utilized or not used
potential
energy in motion
kinetic
branch of physics that focus on the study of heat, energy, temperature, work
thermodynamics
The process by which plants,
algae, and specific bacteria
produce glucose from carbon
dioxide and water in the presence
of chlorophyll, using light energy
and releasing oxygen.
Photosynthesis
Types of consumers
herbivore
carnivore
omnivore
The transfer of the sun’s energy from one producer to consumer as organisms feed on one
another (who-eats-whom
sequence within an ecosystem)
food chain
food chain is also known as ____
energy chain
A group of interrelated food chains
food web
plant eaters
Herbivores
flesh eaters
Carnivores
eat both plant and animals
Omnivores
eat dead carcasses of larger animals
Scavengers
eat litter, debris, dung (detritus)
Detritivores
final recycling of organic materials
Decomposers
Amount of available energy decreases for higher
consumer
Amount of available energy decreases down the
food chain
Energy Pyramid
self producing (plants, algae, bacteria)
autotrophs
other feeder(all animals)
heterotrophs
