What is a habitat |
Habitat is the place where an organism lives |
|
|
At what distance does the earth orbit the sun |
150,000,000 km |
|
|
What is the atmosphere |
The atmosphere is the layer of gases surrounding the earth or another astromonical body |
|
|
What is the composition of our atmosphere |
The atmosphere of our planet is made up of about 78% nitrogen gas and 21% oxygen gas and the remaining 1% of our atmosphere includes Oregon water vapour and carbon dioxide and a variety of other gases |
|
|
Why does earth have an atmosphere and why does the moon not have an atmosphere |
Earths mass create a force of gravity strong enough to hold gases near its surface in contrast the force of gravity over moon is not strong enough to hold gases |
|
|
Why is the atmosphere critical. For life on earth |
The atmosphere acts like a blanket and moderates surface temperatures, the insulation prevents excessive heating during the day and cooling during a night without an atmosphere the temperature of earth would drop from 15°C on average to approximately -18°C. In addition earths atmosphere blocks some incoming solar radiation including most ultraviolet light which is linked to skin cancer without the atmosphere most of earths species would be unable to survive |
|
|
What are the four surface components of earth |
The lithosphere the hydrosphere the biosphere and the atmosphere |
|
|
What is the lithosphere |
The lithosphere is earths solid outer layer.The lithosphere is the Rocky outer shell of earth it consists of the rocks and minerals that make up the mountains, ocean floor and the rest of earths solid landscape, it is between 50-150 km thick. |
|
|
What is the hydrosphere |
The hydrosphere consists of all of earths water in solid liquid and gas form. The hydrosphere consist of all the water on, above, and below earths surface. It includes oceans lakes ice ground water and clouds. Nearly all the water on earth, approximately 97%, is contained in the oceans. |
|
|
What is the biosphere |
The biosphere is the zone around earth where all life can exist. Scientists use the term biosphere to describe the locations in which life can exist within the lithosphere atmosphere and the hydrosphere. Most of the easily observed late for us exist on land and in water, but micro organisms exist several kilometres beneath earths surface |
|
|
What sphere of our planet exists inside the hydrosphere lithosphere and atmosphere |
The biosphere |
|
|
How large is the earth in diameter |
Approximately 12,700 km |
|
|
What is the Gaia hypothesis |
The gaia hypothesis is the idea that the earth through interactions among the biosphere lithosphere atmosphere and hydrosphere behaves like a living organism |
|
|
Which scientist advanced the Gaia hypothesis |
James Lovelock |
|
|
What year did James Lovelock advance the gaia hypothesis |
Somewhere in the 1960s |
|
|
What is an ecosyste |
Scientist define an ecosystem is all of the living organisms that share a region and interact with each other and their nonliving environment |
|
|
What are the two main components in an ecosystem |
Nonliving and living |
|
|
What are biotic factors |
Biotic factors are living parts of an ecosystem, their remains and features, such as Nests, associated with their activities. |
|
|
What are abiotic factors |
The nonliving physical and chemical components of an ecosystem such as temperature, wind, water, minerals, and air. |
|
|
What is a population in terms of biology |
A population is all the individuals of a single species in a particular area or location |
|
|
What is a community in biology |
A community consists of individuals and species from a variety of populations |
|
|
How is an ecosystem considered different from a community |
Ecosystem is the turn given to the community and its interactions with the abiotic environment while the community is just a population of species. |
|
|
What is an aquatic ecosystem |
An aquatic ecosystem is an ecosystem that is primarily based in water or in the hydrosphere |
|
|
What is a terrestrial ecosystem |
A terrestrial ecosystem is the ecosystem that is primarily based on the surface of earth and surface of the lithosphere |
|
|
What is a sustainable ecosystem |
A sustainable ecosystem is an ecosystem that is maintained and regulated naturally through natural processes. They typically maintain a relatively constant set of characteristics over a long period of time. |
|
|
What is the most common way for an ecosystem to be unsustainable |
The most common way that ecosystems change from sustainable to unsustainable is true human activities that change the biotic and abiotic features of an ecosystemm |
|
|
What is sustainability |
Sustainability is the ability to maintain an ecological balance |
|
|
What is radiant energy |
Radiant energy is energy that travels through empty space |
|
|
What type of energy is the source of almost all energy on earth |
Radiant energy |
|
|
What is light energy |
Light energy is all visible forms of radiant energy |
|
|
What is thermal energy |
The form of energy transferred during heating or cooling |
|
|
What is the main source of radiant energy |
The sun |
|
|
What happens to about 70% of the radiant energy that earth collects |
70% of the radient energy is absorbed by the hydrosphere and lithosphere and converted into thermal energy. |
|
|
What happens to 30% of the radient energy that earth collects |
30% of the radiant energy is reflected directly back into space by the clouds or earths surface. |
|
|
What happens to 19% of the radiant energy that earth collects |
19% of the absorb radiant energy is absorbed by the atmosphere and clouds |
|
|
What percentage of radiant energy is absorbed by plants in the process of photosynthesis |
0.023% |
|
|
What happens to 51% of the radiant energy that earth collects |
51% of the radiant energy the earth collects is observed by the land and the ocean |
|
|
What is chemical energy |
Chemical energy is used by all organisms to perform functions including movement, growth, and reproduction |
|
|
What is photosynthesis |
Photosynthesis is the process in which the suns energy is converted into chemical energy for life forms |
|
|
What are producers |
Producers are organisms that make their own energy rich food compounds using the suns energy. all other organisms are consumers |
|
|
What are the bodily organs inside plants that allow them to undergo photosynthesis |
Chlorophyll |
|
|
What is the photosynthesis chemical reaction |
Back (Definition) |
|
|
What is most of the sugar created by photosynthesis converted into. |
Most of the sugar created by photosynthesis is turned into starch for storage |
|
|
Out of the sugar that is not used for storage what is it used for in the process of photosynthesis. |
The rest of the sugar is used as building materials. The carbon, hydrogen, and oxygen into carbon dioxide and water are like building blocks. Using light energy, they are rearranged to form sugars and oxygen gas during photosynthesis, then, components in the sugars are rearranged to form different combinations, for example they form carbohydrates or in combination with nitrogen, proteins |
|
|
What is cellular respiration |
The process by which sugar and oxygen are converted into carbon dioxide and water, to provide energy for the cell |
|
|
What is the equation for cellular respiration |
Back (Definition) |
|
|
What time of day can photosynthesis be used |
Photosynthesis can only be used in the daytime when the sun is out |
|
|
What’s the time period where Can cellular respiration be used |
Unlike photosynthesis cellular respiration is a 24 hour process |
|
|
What are consumers |
Consumers are organisms that obtain energy from consuming other organisms |
|
|
What undergo cellular respiration |
Both animals and plants a.k.a. consumers and producers |
