Vocabulary
The study of how species interact with each other and the environment.
What is Ecology?
These organisms have the property to use sunlight or chemical to produce their own energy.
HINT: All take in energy to assemble energy-rich compounds through photosynthesis and chemosynthesis.
What are Autotrophs or primary producers?
A group of land ecosystems with similar climates and organisms.
What is a biome?
An example of primary producer that float on the ocean surface.
What is phytoplankton?
Animals that eat grasses, clover, as well as roots,seeds, and tree bark Ex. Rabbits are members of a community in a meadow. These organisms share the same trophic level as the rabbits.
What are herbivores?
The community of organisms that live in a particular area, along with their nonliving surroundings. This includes abiotic and biotic factors.
What is an ecosystem?
These organisms are herbivores, therefore they are called ______________ consumers.
What is primary?
The biome that includes regions of several continents. These regions have the same pattern of temperature and precipitation.
What is the dessert?
The chemical process part of the Nitrogen cycle used by bacteria.
What is Nitrogen fixation?
The rule that tells the energy lost in each trophic level. The ecological pyramid describes this rule.
What is the 10% rule?
The living parts and non-living of an ecosystem.
What are biotic and abiotic factors?
These organisms are typically at the top of the food chain. They are called ____________ consumers.
What is tertiary?
Biome that has seasonal variation in precipitation; hot temperatures all year long. Ex: Balem, Brazil
What is tropical rain forest?
Dependent variable
Which of the following is the factor that is observed and measured in an experiment?
When water liquid turns into water gas due to heat increase. Ex. When water goes from the ocean to the atmosphere.
What is a water evaporation?
Two marine ecosystems or zones. The animals on top survive with photosynthesis, the bottom survive with chemosynthesis.
HINT: A submarine diving from the surface into deep ocean water is MOST LIKELY to pass from these zones.
What is photic and aphotic zones ?
This is a model to show how energy in a food web is allocated. Usually there is a large base and a pointed top.
It shows:
1. different trophic levels.
2. The 10% rule at each of the trophic levels.
3. Each tropic level with producer, primary consumer etc.
What is an energy pyramid?
Problem, hypothesis, research, experiment, analyze, conclusion, publish
Which best describes the correct order of the scientific method?
The process of converting nitrates and nitrites are into ammonia. It occurs before denitrification.
What is ammonification?
Include carbon dioxide and methane. They increase air temperatures near Earth’s surface by trapping heat that is radiated from the surface.
What are Greenhouse gases?
A series of events in which one organism eats another and obtains energy. Usually written on one line.
What is a food chain?
A nutrient that limits the productivity of an ecosystem.
What is a limiting nutrient?
List 3 of the 6 major biomes according to the reading in the textbook.
What are the rain forest, desert, grassland, deciduous forest, boreal forest, or tundra?
Carbon (C), hydrogen (H), and Nitrogen (N) are present as gases in the atmosphere.
Phosphorous (P) is not a gas and not present in the atmosphere.
What are the elements present and not present in the atmosphere?
Evaporation comes from water bodies while transpiration comes from plants
How do evaporation and transpiration differ?
