Food Chains and Food Webs
True or False: In a food chain, energy flows in multiple paths. One animal may eat more than one living things.
False
How do animals acquire (get) energy?
By consuming plants or producers
What are the two biomes in which animals are found living in the water? What is the difference between these two biomes?
Freshwater - animals live in salt-free water
Marine - animals living in salty water
Is this relationship true or false?
Producer --> make the food in an ecosystem
Consumer --> eats the food made by a producer
True
Leaves
Producers or autotrophs
True or False: Herbivores are always plants
False. Herbivores are animals that eat ONLY plants.
Different ecosystems around the world are called _________. These ecosystems have distinct features and living systems.
Biomes
True or False: predator prey relationships can be between two animals or one animal and one plant.
False
digestion
Using the following living items - grass, tree, mouse, rabbit, deer, bear, lion, eagle, snake - draw a food web with at least three individual food chains.

The animals that are at the top of a trophic pyramid and have the smallest population are called _________.
Carnivores (technically, predators is also a correct answer)
An ecosystem must have its own (unique)
A) different animal species that are not found elsewhere in the world
B) climate and temperature
C) plants and body of water
D) climate and living system
D
What do herbivores eat?
Plants (producers) only
Which gas do plants breathe in?
What do trophic pyramids, food chains, and food webs show?
Is the sun necessary for animals and plants in an ecosystem to survive? Explain why or why not.
The sun is necessary because plants need the sun to grow. Since, plants are necessary for animals to survive, the sun is indirectly needed for them to survive too. Therefore, the sun is necessary for an ecosystem to exist.
What is one similarity and one difference between the taiga and the tundra.
Similarity: both are snow covered and extremely cold.
Difference: the tundra is barren and has no trees, while the taiga has many coniferous trees.
What is the difference between an omnivore and carnivore?
Carnivore - eats only animals
What do plants make when they produce food? (in other words, what is plant food called?)
Glucose (sugar)
Using the following information,
1. Construct a trophic pyramid and food chain
2. Identify which animals are producers, herbivores, carnivores, and omnivores.
Information: A mouse eats a plant. The mouse is eaten by a snake (which also eats the plant) and the snake is eaten by an eagle. The mouse is also eaten by a cat, which in the ecosystem has no predators.

Producer: plant
Herbivores: mouse
Omnivore: snake
Carnivore: eagle and cat
Are there more predators or prey in an ecosystem? Explain why your answer makes sense.
There are always more producers so that each of the prey have a food source. If there were more predators, the prey would go extinct which would eventually cause the predators to die too (from starvation). Having more prey than predators is necessary for an ecosystem to exist.
Explain how animals that are found in multiple biomes are different and provide one example.
Frogs can be found in a freshwater biome or a rainforest. Even though the same species (frog) is in both biomes it has different predators depending on where it lives. For example, a frog in a freshwater ecosystem might be the prey of an alligator while it might be the prey of a snake in the rainforest. Additionally, the species would look different so they can best survive in either ecosystem. Lastly, because of the geographic differences in the regions, the species would have different food sources.
Explain the difference between an autotroph and a heterotroph.
Autotroph - producer
Heterotroph - consumer
The process plants use to make food is called
photosynthesis
