What are the 3 things you learned from the ecosystem video?

Comment down below. Please write your full name and section.

I discovered that an ecosystem is a community of living and non-living things that interact with each other. It’s made up of plants, animals, people, air, water and sunlight. There are roles that each part of the ecosystem plays in maintaining balance in nature. Land and water systems exist, such as forests and oceans. I have also learnt that we should take care of our ecosystem to be protected nature without pollution

components of there environment.

Ecosystem includes two major components Biotic and Abiotic components Abiotic components are the non-living elements of the system such as air, water, sunlight,nutrient, and temperature Biotic components are the living organisms living in the system like plants, animals, fungi, micro organism,and You

Prey are the animals that Predators eat,and dr.bionics said Prey can't eat or attack Predators since one must be extinct or leave.

Abiotic is a non living components like air, water, sunlight, nutrients,and temperature.

Biotic is a components that is a living organism like plants, animals, fungi,micro organism, and humans.

I learned that an ecosystem is made up of living and nonliving things that work together and depend on each other to survive. I also learned that every organism has an important role in keeping the ecosystem balance

The Coral Reef Ecosystem

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. They are often called the "rainforests of the sea" due to their high biodiversity and complex interactions.

- Key Components:

- Abiotic Factors:

- Sunlight: Essential for photosynthesis by zooxanthellae (algae) living within coral tissues.

- Water Temperature: Corals thrive in warm, clear, and shallow waters, generally between 20-30°C.

- Salinity: Stable salinity levels are necessary for coral health.

- Water Clarity: Clear water allows sunlight to penetrate, supporting photosynthesis.

- Biotic Factors:

- Producers (Autotrophs):

- Corals: The primary reef builders, containing symbiotic algae called zooxanthellae that provide them with energy through photosynthesis.

- Algae: Including macroalgae (seaweeds) and phytoplankton, which also contribute to primary production.

- Consumers (Heterotrophs):

- Herbivores: Fish (e.g., parrotfish, surgeonfish) that graze on algae, keeping algal growth in check.

- Carnivores: Fish (e.g., sharks, barracudas), invertebrates (e.g., crabs, sea stars), and other animals that prey on other organisms in the reef.

- Omnivores: Some fish and invertebrates that consume both plants and animals.

- Decomposers: Bacteria, fungi, and other microorganisms that break down dead organic matter, recycling nutrients.

- Interactions and Relationships:

- Symbiosis:

- Mutualism: The relationship between corals and zooxanthellae, where corals provide shelter and nutrients to the algae, and the algae provide energy to the corals through photosynthesis.

- Commensalism: Small fish or invertebrates that live within corals for protection without harming the coral.

- Predation: Carnivorous fish preying on smaller fish, or sea stars preying on corals.

- Competition: Competition for space and resources among corals and other reef organisms.

- Energy Flow and Nutrient Cycling:

- Energy Flow: Sunlight is captured by zooxanthellae and algae, converted into chemical energy, and then transferred through the food web as organisms consume each other.

- Nutrient Cycling: Nutrients are cycled within the reef ecosystem, with decomposers breaking down organic matter and releasing nutrients back into the water.

- Importance and Value:

- Biodiversity Hotspot: Coral reefs support a vast array of marine life, providing habitat, food, and shelter for countless species.

- Coastal Protection: Reefs act as natural barriers, protecting coastlines from erosion and storm damage.

- Economic Benefits: They support fisheries, tourism, and recreation industries.

- Nutrient Cycling: Reefs play a role in nutrient cycling and maintaining water quality.

- Threats and Conservation:

- Climate Change: Rising ocean temperatures cause coral bleaching, where corals expel their zooxanthellae and become stressed.

- Ocean Acidification: Increased CO2 levels in the atmosphere lead to ocean acidification, which hinders coral growth and skeleton formation.

- Pollution: Runoff from land, including pollutants such as fertilizers, pesticides, and sewage, can harm coral reefs.

- Overfishing: Removal of key species can disrupt the balance of the reef ecosystem.

- Destructive Fishing Practices: Blast fishing and cyanide fishing damage coral structures and harm marine life.

- Conservation Efforts: Establishing marine protected areas, reducing pollution, promoting sustainable fishing practices, and restoring damaged reefs.

- Local Perspective (Philippines - Davao): The Philippines, including Davao, is part of the Coral Triangle, which is known as the "Amazon of the Seas" due to its high marine biodiversity. Local conservation efforts focus on protecting coral reefs through marine reserves, sustainable tourism, and community engagement.inable tourism, and community engagement.

There are many example abiotic and biotic,and more.Abiotic is an elements of non living.And biotic elements can be as any living components that affect other organism or shapes the ecosystem.

AN ABIOTIC ELEMENTS ARE NON LIVING THINGS . AND BIOTIC ELEMENTS CAN BE ANY LIVING COMPONENTS.
