QUICK EXAM 5

2nd law of thermodynamics: "Energy can be neither created or destroyed, it can only be transformed"

The variety of life in every organization level

Deforestation, agriculture, stockbreeding, mining or urban development causes a biodiversity loss

CONANP is in charge of the federal natural reserves

Carbon is transformed by bacterias into Carbon dioxide

The efficiency of energy transfered from one throphic level to the next one is about 1%

Australia is one of the top 5 mega-diverse countries

The Oxygen cycle is also part of the water cycle

Endemic specie is native to a single defined geographic location, such as an island, state, nation, country, etc....

The products of the photosynthesis are:

"organic matter" specially plant matter that can be used as fuel or energy source

Primay producers are usually the hervivores

Biogeographic areas that are representative of two or more ecosystems that hadn´t been altered by human beings

Products of the respiration are:

Consumption patter society when the human started to cultivate and domesticate animals

Nitrogen can be directly absorbed/assimilted by organisms

These systems are more common. There´s an exchange of energy and matter.

The way in which organisms are organized within the ecosystem according to the type of food they consume

This science studies the processes related to the exchange of heat and energy

The energy flow travels through components of the ecosystem

A series of practices aimed to the restoration of the structure and operation of the affected ecosystems.

"Each time energy is transferred, a portion of it is used as a form of work, while the rest is lost as heat"

Phosphorus is used by the plants as a nutrient, next to the nitrogen, it defines wheter a soil is fertile or not.

Acid rain results when sulfur dioxide and nitrogen oxides are emitted into the atmosphere.

These resources do not regenerate once they are substracted from nature so they will decrease little by little.

Types of biomass except....

Plants only use 1% of energy from the 100% produced by the sun

There are 5 major categories of biomes which are these: except......

“terrestrial or aquatic areas in which the original environment has not been modified"

Human activities such as agriculture, grazing, logging and lack of water are not related to desertification

This type of energy keeps you warm

Monera kingdom are multicellular organisms performing the photosynthesis.

Plants need this for the photosynthesis

The first source of energy is the sun
