They point to the organism that is being eaten.
It shows how sunlight flows within an ecosystem.
They show the direction the energy is flowing between organisms.
They represent how water is transferred within a habitat.
Consumers that eat only plants
Carnivores
Omnivores
Herbivores
Scavengers
Consumers, such as vultures, that feed on the bodies of dead organisms
Carnivores
Omnivores
Herbivores
Scavengers
A food _______ is a series of events in which one organism eats another and obtains energy.
chain
web
pyramid
plate
Which process do plants use to turn sunlight into food energy?
photosynthesis
cellular respiration
transpiration
evaporation
Which organism is an example of a producer?
moth
mushroom
rose bush
cheetah
Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach?
Plants are not infinite in number.
Producers are limited by consumers.
Carnivores are too large to be eaten.
Energy is lost at each trophic level.
"Bio-" means
life
water
Earth
air
Into which trophic level will herbivores most likely be placed?
X
W
Y
Z
Which would most likely happen if the Bluegill population decreased significantly?
The Zooplankton population would start being consumed by the Kingfisher population.
The Crayfish population would compete with
the Minnows for food.
The Minnows population would decrease in number.
The Kingfisher population would decrease in number.
Which is the correct representation of energy flow through an ecosystem?
sun → autotrophs → heterotrophs
water → squirrel → nuts
sun → consumers → producers
autotrophs → heterotrophs → sun
As energy flows through each trophic level of the food chain approximately what percentage of energy is available to the next trophic level?
100%
10%
1%
50%
In this food chain
Algae → Zooplankton → Small fishes → Squid → Shark
The Algae at the beginning of the food chain are
Decomposers
Consumers
Heterotrophs
Producers
Algae generate 84,000 kcals of tissue. Which represents the amount of energy available for primary consumers in the food chain?
84,000 kcals
8,400 kcals
840 kcals
84 kcals
If only 10% of the energy in the pyramid is available as you move from one trophic level to the next, what happens to the other 90%?
Passed on to decomposers
Metabolized and "lost" as heat energy and waste
Assembled into tissues of producers permanently
False statement - 100% of the energy is available
What level consumer is the frog
Primary Consumer
Secondary Consumer
Tertiary Consumer
Apex Predator
