Ecosystems and biomes
Ecosystems are all of those systems conformed by ______ communities related to their _______ environment in which they interact.
Biotic/ Abiotic
It refers to the velocity in which the material produced by an organism is decomposed into smaller chemical components.
Decomposition rate
From that 100%, only __% is captured by plants and other photosynthetic organisms, which transform solar energy into biomass energy that is going to pass through the food chain.
1%
There are relationships among living beings where the energy is transferred from an organism to another, it is also called food chain
Trophic webs
The water cycle is also called ______________
Hydrologic cycle
Mention two of the five major categories of biomes:
Desert/ aquatic/ forest/ grassland/ tundra
It refers to the way in which organisms are organized within the ecosystem according to the type of food they consume.
Tropic structure
Our planet depends on the energy from the _____
Sun
Mention one of the levels from the food chain:
Producers/ Primary consumers or herbivores/ Secondary consumers or small carnivores/ Tertiary consumers of mayor carnivores
Mention one of the macronutrients that are fundamental for living beings:
Carbon, hydrogen, oxygen, nitrogen, phosphorous or sulfur
Why does Mexico has a great variety of ecosystems?
Because its geographical location
It is the measurement of energy passing through trophic levels. Energy percentage produced by a plant and the amount transferred to another organism.
Ecological efficacy
Energy can be neither _____ nor _____, it can only be _______
Created/ destroyed/ transformed
It is the first level from the tropic web, they are photosynthetic and chemosynthetic autotrophic organisms like plants and algae.
Producers
This cycle is performed when photosynthesis occurs and plants take carbon dioxide and solar light in order to produce oxygen.
Oxygen cycle
It refers to a very large ecological area with fauna and flora adapted to their environment, also IT is defined by abiotic factors such as climate, relief, geology, soil and vegetation.
Biomes
It is the measure of the rate at which new organic matter is developed through photosynthesis and chemosynthesis in producer organisms.
Primary productivity
It can be defined as the capacity performed a certain work
Energy
It is the second trophic level, they feed on producers such as cows.
Primary consumers or herbivores.
This element moves across the atmosphere through photosynthesis, it also moves in the lithosphere through decomposition of dead organisms and as a waste product.
Carbon
Mention one of the components of ecosystems:
Producers or autotrophs/ consumers or heterotrophs/ decomposers
It is the rate at which consumers convert chemical energy from their food into their own biomass.
Secondary productivity
Each time _____ is transferred, a portion of it is used as a form of work, while the rest is lost as heat
Energy
Name one of the types of trophic pyramids:
Pyramid of energy/ Pyramid of biomass/ Pyramid of numbers
These cycles are performed on the terrestrial crust where the nutrients or chemical substances move between the rocks, ground or minerals. These cycles are very slow, for these substances remain across thousands or millions of years within sedimentary rocks.
Sedimentary cycles
