Question 1:
The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.

$Producer$
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.

$Producer$ ⇒ $Herbivore$
The carnivore consumes meat, or other animals such as the herbivore. It's the last.

$Producer$ ⇒ $Herbivore$ ⇒ $Carnivore$
Therefore the answer is B.

Question 2:
I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.

Identify a structure other than a cell wall or a vacuole that might be found in a plant cell but not in an animal cell. explain

enot [183]

One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.

Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.

Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.

What was one of the most important steps in the evolution of early living things?

Aneli [31]

Answer: the development of the enzyme Rubisco and evolution of oxygenic photosynthesis.

Explanation: One can pick many key steps in early evolution: the development of the first cells, oxygenic photosynthesis, endosymbiosis leading to eukaryote organisms.

One important step was the mutation to the enzyme ribulose bisphospate carboxylase oxygenase (Rubisco) which enabled oxygenic photosynthesis.

The cyanobacteria that had Rubisco changed the planet’s atmosphere by producing oxygen as a by-product of photosynthesis. They were the most successful organisms of the time and have continued as a successful and ubiquitous group of organisms for billions of years.

The production of oxygen changed the direction of evolution profoundly. Later endosymbiosis led to the evolution of plants, with cyanobacteria the ancestors of chloroplasts, making Rubisco one of the most common enzymes on the planet.
