Origins of Birds
How many species of birds are out there right now?
There are 10,000 species of birds nowadays.
What is carbon cycle
Carbon cycle is when carbon in CO2 is incorporated into plants by photosynthesis, then into animals by consuming organisms, and returned to the air as CO2 from respiration. Cellular carbon is returned to the soil through waste and dead organism decay.
What is evolution?
Evolution is when different kinds of creatures are thought to have developed overtime from ancient creatures on Earth.
What is slash and burn?
Slash and burn was a technique where all trees are cut down and the area is farmed. After the area is farmed the place is burned enriching the soil.
What is natural selection?
Darwin's theory which says that organisms best adapted to their environment are more likely to survive and pass on their traits to their offspring.
Are modern birds descendent from pterodactols?
No they don't come from pterodactols.
What does sunlight give to plants during the carbon cycle?
The sunlight gives plants to do photosynthesis.
Who came up with the theory of evolution?
Charles Darwin
Why was slash and burn used?
Farmers used this method car space to grow more crops.
Who came up with natural selection?
Charles Darwin
What similarities do a chicken and a T-Rex have in common.
A chicken and a T-Rex have in common is that they have three main claws in the front and one small toe in the side.
What is fossil fuel?
Fossil fuel is when plants die and get buried and turn into fossils fuels made of carbon like coal or oil overtime. When you burn the fossil fuels, the carbon goes into the atmosphere as carbon dioxide and that creates a green house effect.
What is human evolution?
Human evolution is a theory that modern day Humans had evolved from ancient apes.
What areas is slash and burn used in?
Slash and burn is usually used in areas were there is a lot of trees and plants.
Why does natural selection happen?
Natural selection happens when a creature needs to adapt to something in order to survive. Also when the environment changes, the creatures need to change as well.
What re Theropods?
Theropods are dinosaurs that are walk with two legs, warm blooded, and agile.
Birds evolved from Theropods.
What process removes carbon from the atmosphere?
Photosynthesis
Why does evolution happen?
Evolution happens when a creature needs to adapt or change when time changes overtime. For example when a creature begins to live in a snowy terrain, but then as thousands or millions of years pass by, the creature needs change by the color of its fur or having its fur to be more thicker to survive the coldness.
What climate effect can slash and burn have on the environment?
Slash and burn can throw carbon dioxide into the air which can cause the climate to change and global warming.
What benefit can natural selection do to animals or plants?
Natural selection helps animals and plants survive because they changed from before.
What was the name of the fossil discovered that provides evidence that birds being descendent from dinosaurs?
Archaeopteryx
Why is the carbon cycle important?
The carbon cycles important because carbon dioxide present in nature is used by plants during photosynthesis to form glucose and carbohydrates is known as carbon cycle
What are three evidences of evolution?
Three evidence are fossils, homologous structures, and vertical structures.
What is a benefit for slash and burn farming?
A benefit for slash and burn farming is that the ash provides instant fertilization that only a tractor could offer.
How long does natural selection take to occur?
It takes about one million years.
