Food Chain and Food Web Flashcard

Front

What do the arrows in the diagram represent?

Back

how energy flows between organisms

Front

Analyzing the picture, what would happen to the populations of the organisms if you were to remove the producers?

Back

The primary, secondary, and tertiary consumers would eventually starve and die off.

Front

Which organism can be both a primary and secondary consumer? Options: Mice, Foxes, Carrots, Birds

Back

Front

Which organism is considered a tertiary consumer? Options: Mice, Foxes, Grasshopper, Grains

Back

Foxes

Front

Impact of humans on the carbon cycle: How do humans add and return carbon to the environment?

Back

Humans add carbon dioxide to the atmosphere when they undergo cellular respiration, burn fuel in cars and factories and burn biomass. They take in carbon from the food they eat and return it to the soil through waste products and decomposition.

Front

Impact of the industrial revolution on the carbon cycle based on figures?

Back

The industrial revolution has decreased the amount of carbon stored in the soil by the removal of fossil fuels. It has also increased the amount of carbon in the air by the burning of fossil fuels and removal of trees for the expansion of cities.

Front

Isabel needs an image to represent the carbon cycle for a presentation in her science class. She has the following diagrams to choose from. Based on the information represented in the concept models above, which statement is true?

Back

Model D would be the best for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place.

Front

How do herbivores contribute to the carbon cycle from the food they eat?

Back

Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.

Front

What has happened to the other 45% of carbon dioxide not absorbed by plants and oceans since the Industrial Revolution?

Back

It has stayed in Earth's atmosphere, acting as a greenhouse gas.
