Ecology Review

Master ecology concepts! Review levels, cycles, symbiosis, food webs, and energy pyramids.

List the levels of ecology from the smallest (most specific) to the broadest Organism --> Population --> Community --> Ecosystem --> Biome --> Biosphere Match the description with the appropriate level of ecology: A single ant organism A colony of ants Population The ants, grass, and flowers found in a certain area Community The ants, grass, flowers, sun, and soil in a certain area Ecosystem A group of biotic and abiotic factors that share a similar climate and weather patterns Biome The portion of the earth that supports life Biosphere Add the missing levels using the words listed below. In order to receive credit the word needs to be typed in lowercase and spelled correctly, just like the word bank!! WORD BANK: atom, biosphere, cell, community, ecosystem, molecule, organ system, organelle, organism, organ, population, and tissue atom biosphere molecule organelle cell ecosystem community tissue organ population organ system organism The main difference between a community and an ecosystem is that a community only includes biotic factors whereas ecosystems include biotic and abiotic factors The images below are larger versions of the ones you have to sort. Use these to help you see the difference between the two. Primary Succession (8) no soil present longer form of succession starts with bare rock caused by volcanoes lower biodiversity to start created by retreating glaciers pioneer species most likely lichen mosses Secondary Succession (7) soil is present quicker form of succession greater biodiversity to start caused by forest fires, tornadoes, hurricanes caused by deforestation pioneer species most likely grasses small plants From what kingdom is the organism that plays a major role in the nitrogen cycle performing nitrogen fixation and denitrification? Plantae Animalia Eubacteria Protista As part of the nitrogen cycle, animals acquire(take in) nitrogen by doing which of the following? breathing air eating plants drinking water producing waste Use the image of the carbon cycle to help you sort the processes that absorb and release carbon to and from the atmosphere. Carbon is Released into the Atmosphere respiration by plants animals burning of fossil fuels burning of forests erupting volcano Carbon is Absorbed from the Atmosphere photosynthesis by producers dissolving in the ocean decomposition of dead material into soil or sediment rocks Symbiosis Review In the table below, use the drop-down box to provide a definition and example of each type of symbiosis. The images will go in the row titled symbols Definition Mutualism Parasitism Commensalism Definition Symbiotic relationship where both organisms benefit Symbiotic relationship where one organisms benefits by harming another organism known as the host Symbiotic relationship where one organisms benefits and the other is neither helped nor harmed Example Ex: Certain birds life on buffalo and eat insects and parasites off of the buffalo Ex: A wasp injects its eggs into another organism and steals the organisms nutrients Ex: Small fish swim under bigger fish for protection Symbols Use the word bank to complete the sentences below: 1. A producer is an organism at the beginning of a food chain because they can produce their own food using energy from the sun2. Organisms that feed off of other organisms and cannot make their own are known as heterotrophs3. A nonliving part of the environment is a(n) abioticfactor4. A living part of the environment is a(n) biotic factor5. A consumer that eats only plants is known as a herbivore6. A consumer that eats both plants and animals is called an omnivore7. Energy is transferred through an ecosystem by eating or consuming food and is represented on food chains and food webs using arrows8. Decomposers breakdown decaying organisms and nutrients are put back into the soil by bacteria and fungi Food Chains and Food Webs Use the following food chain to answer the questions below: - The arrows represent energy - In this food chain, which organism is the producer? grass - In this food chain, which organism is the primary consumer? grasshopper- In this food chain, which organism is the tertiary consumer? snake- In this food chain, which organism is an herbivore? grasshopper - What type of consumers are the frog and the snake? carnivores- If the frog population increased, what would happen to the grasshopper population? decrease- If the frog population increased, what would happen to the snake population? increase- Which organism has the highest amount of energy? grass- Which organism has the lowest amount of energy? snake- What was the original source of energy in this food web? Sun Use the food web below to answer the following questions What level of consumer is a wild cat? Primary Consumer Secondary Consumer Tertiary Consumer Both Secondary Tertiary Consumer What level of consumer is a goat? Primary Consumer Secondary Consumer Tertiary Consumer Producer Which organism can be both a primary and a secondary consumer? Owl Wild Cat Rabbit Snake What kingdoms are missing from the food web that play a critical role in breaking down matter so nutrients can be recycled? ? Plantae Bacteria Fungi Animalia Protista This food chain can be found in the coastal waters of Virginia. The population of which organisms in the food chain would be the first to decline if commercial fishing over-harvested shrimp? Algae Zooplankton Damselfish Barracuda Terrestrial Food Web Correctly tag the organisms in the food web as a producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer. Be sure to use all lowercase letters and no "s" at the end and the words can be used more than once. Below is the number of times you should use each word.1 Producer3 Primary Consumers6 Secondary Consumers4 Tertiary Consumers1 Quaternary ConsumerHint: Tag the plant as "producer" and go from there! Also, don't forget animals with more than one tag can be more than one type of consumer. quaternary consumer tertiary consumer secondary consumer primary consumer primary consumer primary consumer secondary consumer secondary consumer tertiary consumer tertiary consumer secondary consumer secondary consumer tertiary consumer secondary consumer producer Label the following energy pyramid using the word bank provided and then apply the 10% law to the energy pyramid based on the information given. Use the following words to fill in the trophic levels on the energy pyramid: decomposer, tertiary consumer, secondary consumer, primary consumer, producer Be sure to use all lowercase letters and no "s" at the end.The producers will start with 10000J of energy. Type 10000J on the label button to the right of the producer section on the energy pyramid and then complete the above label buttons applying the 10% rule. Make sure your number format follows this example 10000J (Number, capital J, no spaces) producer primary consumer secondary consumer tertiary consumer decomposer 10000J 1000J 100J 10J Review some of the environmental changes that can disrupt and impact the stability in an ecosystem.
