What is photosynthesis?
A process that transforms solar energy into chemical energy
of organic nutrient molecules
What process is required by the majority of life on Earth?
Photosynthesis
What defines how an ecosystem functions?
Energy and chemical flow between organisms
,What is chemical cycling?
Occurs as chemicals move from one population to another
in a food chain until death and decomposition allow
inorganic nutrients to be returned to the producers once
again
What can ecosystems not function without?
Ecosystems can not functions without input of solar energy
and the presence of photosynthetic organisms to absorb it
How does energy become heat?
Flows from the sun through plants and other members of the
food chain as they feed on one another, then gradually
dissipates and returns to the atmosphere as heat
Life only comes from what?
Life
,Do all forms of life have the capability of reproduction?
Yes
How do bacteria and simple celled organisms reproduce?
Split into two to reproduce
How do multicellular organisms reproduce?
By the pairing of sperm from one partner and an egg from
the other partner
What happens when living organisms reproduce?
Their genes are passed in random combinations from the
sperm and egg, creating an unique collection of gene
What does DNA provide?
The blueprint for characteristics of a particular organisms
, All cells in multicellular organisms contain the same set of
genes, but...
Only certain genes are turned on in each type of specialized
cell
When does development start?
At the union of the sperm and egg
What is development?
The process of becoming an adult
What is a mutation?
A variation in genetic material
Why are mutations important?
Play an important role in how organism ultimately adapt to
their environment (Not all mutations are bad)
