Answer: Option B
<u>Explanation:</u>
In science, the term species alludes to all creatures of a similar kind that are conceivably skilled, under regular conditions, of rearing and delivering rich posterity. The individuals from an animal type living in a given zone simultaneously comprise a populace. Every one of the populaces living and interfacing inside a specific geographic zone makes up a natural (or biotic) community.
The living life forms in a network together with their nonliving or abiotic condition make up an ecosystem. In general, an ecosystem it can be as little as a couple of mosquito hatchlings living in a downpour puddle or as huge as prairie extending crosswise over a huge number of kilometers.
The blood cells and blood vessels belong to the cardiovascular system.
<h3>What is the Cardiovascular system?</h3>
The cardiovascular system, also known as your circulatory system, is made up of numerous blood veins throughout your body. Your heart uses the extensive, complex network of blood arteries to carry oxygen and other essentials to every part of your body. Additionally, this network takes away items that your body doesn't require and transports them to organs that can dispose of waste. Your entire body receives oxygen, nutrients, and waste through your blood.
The cardiovascular system's job is to make sure that your body gets the nutrition, oxygen, and other things it needs while eliminating the items it doesn't.
Even when you are asleep, your heart is still pumping blood throughout your body. This explains how your doctor can hear your heartbeat. Your heart is making that sound as it works. Every day, your heart pumps around 2,000 liters of blood.

How and where do plant and animal cells get their energy? Let's find out!
° Plant cells get their energy through photosynthesis. This means that they have a green chemical in them called chlorophyll that works like a million solar panels.
° Animal cells get their energy from the food that they eat. They take Glucose (a type of sugar) and turn it into a chemical known as ATP which is what they use for energy!
Science is so cool, isn't it? :)
