| Food Chains, Food Webs, and Energy Pyramids | ||
| #1 | In the food chain below what would increase the energy for the Hawk?
Plant->Beetle->Catfish->Hawk |
an increase in catfish |
| #2 | An arrow that points toward another organism tells you that the organism the arrow came from is its ___________. |
Prey |
| #3 | In an energy pyramid if there are foyr levels and the producers contain 1100 Kcal of energy an orgaism in the level above them would recieve how much energy? |
110.0 Kcal |
| #4 |
In this energy pyramid what level would have the smallest number of organisms in it?Why? |
Level 4
Larger consumers usually have fewer offspring. |
| #5 |
Which organisms are in each trophic level in this food web?
|
Producers-Carrots, Grasses. Grains Primary Consumers- Rabbits, Mice, Grasshoppers Secondary Consumers- Birds, Owls Tertiary Consumers- Foxes |
| Phtosynthesis Reactants and Products | ||||||
| #1 | The gas that is absorbed during photosynthesis is ______________. |
Carbon Dioxide |
||||
| #2 | The gas that is a product of photosynthesis is ______________. |
Oxygen |
||||
| #3 | What is the food called the plant makes? |
Gluscose |
||||
| #4 | The sun provides plants with _______________. |
Radiant Energy |

| #5 | 1. Photosynthesis is the process by which plants convert –
|
|

| Trophic Levels | ||
| #1 | What are the four different trophic levels we learned? |
Producers Primary Consumers Secondary Consumers Tertiary Consumers |
| #2 |
Which organisms are your primary consumers? |
Shrimp Copepods Pteropods |
| #3 |
What are the secondary consumers in this food web? |
Lizard Bird (not eagle) |
| #4 |
What is the highest and lowest number of Trophic Levles are in the chains of this food web? |
5 highest(tree,mouse,rabbit,wildcat, lion)
3 lowest(Tree, goat, Lion) |
| #5 | How does energy change from one trophic level to the next? |
Only 10% is stored by the organism in the next trophic level above an organism right below them. |
| Phtosynthesis in General | ||
| #1 | 1. Plants need radiant energy and which of the following |
Carbon Dioxide and water |
| #2 | Green plants capture and store light energy from the Sun |
Photosynthesis |
| #3 | 1. The energy plants gain through photosynthesis is stored in – |
Glucose |
| #4 | Glucose helps maintain life on our planet by storing – |
Chemical Energy |
| #5 | What type of energy does the sun provide to plants? |
radiant energy |
| Energy Flow in General | ||
| #1 |
What is one food chain in the food web above? |
Green Plant->Goat->Jackal->Lion
This is one example there are many. |
| #2 |
What level of light produced the most oxygen? |
High |
| #3 | They break down plant and animal remains and waste into molecules that producers reuse to make energy. |
Decomposers |
| #4 | A rabbit (primary consumer) is preyed upon and consumed by a fox (secondary consumer). Before being consumed, the rabbit had eaten leaves and berries. The leaves and berries contained 20 kJ of energy. How many kilojoules of the energy from the leaves and berries did the fox obtain after eating the rabbit? |
.2 kj |
| #5 |
In the picture which organism would most benifit from an increase in frogs? |
Raccoons |
| Final Question | |
Producers get energy by ... |
making their own food |
