We
all know that vascular plants really have many advantages. These refer to trees
and flowering plants which really gives us what we need. While nonvascular
plants are those small and simple plants which do not have any phloem or xylem.
Despite nonvascular plants do not have as many advantages as the vascular plant
to the people. They still played a big function in our ecosystem. For example,
the algae, algae serve as the food of some of fishes in the pond or lakes. Non-vascular
plants are also involved in processes like decomposition and indicators.<span>

The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:
1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit
2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake
3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)
They are the opposite of each other.
Photosynthesis requires carbon dioxide and releases oxygen, Cellular respiration requires oxygen and releases carbon dioxide.
