The document discusses key aspects of ecosystems, including the definition of an ecosystem as a whole community of organisms and their environment. It describes the components of an ecosystem and the symbiotic relationships between organisms, noting that all organisms rely on others to live. The document also covers energy flow through ecosystems in the form of food chains and pyramids, and how the amount of energy decreases at each trophic level. Finally, the reporters challenged listeners to consider how to preserve and protect Earth's ecosystems, as Earth is the only planet capable of sustaining life.

The first reporter discussed about the Ecosystem wherein he gave the overview or
wholeness of an ecosystem and its definition. They also talked about the different components of
ecosystem and the symbiotic relationship of all organisms living in a particular ecosystem. They
emphasized that all organisms needs other organism for them to live. Meaning, in an ecosystem
there is a give and take relationship among all organisms.
The next topic they discussed is the energy flow and pyramids of energy were they
showed through a slide on how the energy passes through the different level of consumption. The
biggest amount of energy was acquired by the primary consumer while the last consumer
received or acquired the lease amount of energy. Like we human as secondary consumer we only
acquired 90% of energy from the plant.
