please helllppp
Answer:
A. Sunlight
Explanation:
Answer:
A. Sunlight
Explanation:
It is A because sunlight is nonliving, and an energy source (producer).
is Bacteria used in photosynthesis.
Answer:
They carry out oxygenic photosynthesis i.e, they use water as an electron donor and generate oxygen during photosynthesis. Their photosynthetic systems closely resembles to that of eukaryotes: These bacteria use Phycobilins as accessory pigments. CO2 in these bacteria is assimilated through calvin cycle.
Explanation:
Answer:
NO

What leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions?
A. less biodiversity
B.smaller food webs
C.greater biodiversity
D.specialist consumers
Answer: I think it’s C
Explanation: more biodiversity, the more reproduction and success.
Greater biodiversity leads to the likelihood that there are successful traits in an ecosystem. Therefore, option (C) is correct.
What is biodiversity?Biodiversity refers to the variety of species and the genetic diversity within those species that exist within an ecosystem. When an ecosystem has high levels of biodiversity, there is a greater chance that at least some species will have the traits necessary to survive and reproduce in changing conditions.
Organisms with successful traits in one set of conditions may not necessarily have those same traits in different conditions. Therefore, a diverse range of species with various sets of traits increases the likelihood that some of those traits will be beneficial in different conditions.

Describe the structure of the study independent variables , dependent variables and detail why the researchers would have used random allocation.
Answer:
To reduce systematic error.
Explanation:
The researchers would have used random allocation in order to decreases systematic error in the experiment. If we don't apply random allocation to the experiment, there is high chances of systematic error in the experiment and the result is not of high quality. Independent variables is a type of variable whose variation does not depend on another factor while on the other hand, dependent variables is a type of variable whose variation depend on another factor.
