Symbiosis
In mutualism how many organisms are harmed?
None
What is the difference between a food web and food chain?
A food web is made up of many chains. Chains are a step by step sequence where a food web is more representative of the ecosystem.
What is the word equation for photosynthesis?
Carbon Dioxide + Water --> Glucose + Oxygen
What are the pioneer organisms that first in habit an area after a volcano erupts?
Moss and Lichens
This prokaryotic organism aids in converting nitrogen in the ground into a usable from of nitrogen in a process called nitrogen fixation. What type of organism is it?
Bacteria
When one organism EATS another this is known as...
Predation
What type of organisms provide the most energy in an ecosystem?
Producers/Plants
When a plant grows toward the sunlight this is known as what kind of tropism?
Phototropism
What is the first plant to emerge in secondary succession?
Grass
How have the ice caps changed in the last 50 years?
They have melted causing the ocean levels to rise
Hermit crabs live inside shells produced by other organisms. Sea anemones often attach to the top of a hermit crab's shell. When the crab moves, the shell, including the anemone is carried to a new location. There may be additional food resources at this location. Most predators of hermit crabs avoid sea anemones. Which symbiotic relationship best describes the hermit crab and sea anemone?
Mutualism
Where does all of the energy in a food chain/ food web originate from?
A plant closes its leaves inward in response to touch, this is called thigmotropism. Why might this plant have this adaptation?
To make itself less appealing to herbivores.
True or False:
The difference between primary and secondary succession is the type of climate a natural disaster occurs in.
False
Bacteria play in an important role in the nitrogen cycle by fixing nitrogen. They can also break down dead organic material. What are organisms called that can do this process of breaking down and transforming material?
Decomposers or Detritovores
Leeches are organisms that feed on their host blood. This is an example of what type of relationship?
Parasitism
If producers in a food pyramid contain 60,000 KJ of energy, how many KJ would be found in secondary consumers?
600 KJ
Thick fleshy stems with thick waxy covering would most likely be useful adaptations for plants that might live in what location?
A desert environment where it can retain in moisture to prevent water loss.
Give 2 examples of how an ecosystem would enter the stages of secondary succession.
•Forest Fire
•Deforestation
•Tornado
•Hurricane
What cycle is most closely related to climate change?
The Carbon Cycle
When barnacles attach themselves to a whale, the whale is not usually positively or negatively affected. The movement of the water past the swimming whale carries food particles to the barnacles. This situation is an example of –
Commensilism
Which way is the arrow drawn in a food web/chain diagram?
Toward the organism doing the consuming.
What stage of the cell cycle does DNA replication occur?
S stage, during interphase
In your own words, describe succession.
