It is the study of the interactions among organism and their environment. 

This is a community of a biotic components that interact with each other. 

This refers to non-living parts, such as weathers, soil, rock, and sun. 

This refers to all organism such as plants, animals, and bacteria. 

This organism manufactures their own  food.

An organism eats dead organisms. 

An organism that breakdown dead bodies of an organism. 

This terrestrial ecosystem found in wet tropical uplands and lowlands near Earth's equator. 

This layer of trees in tropical rainforest has enormous umbrella shape-trees that take up plenty of sunlight.  

A parasite species of Lianas. It is endemic plant to the Philippines. 

This is the darkest layer in the rainforest. 

What do we call the long-term relationship that exist between two organisms? 

What relationship shown by a frog eats insects using their sticky tongue? 

A type of relationship wherein two organism benefit from each other. 

A type of relationship wherein two animals fight for the same food. 

A type of relationship wherein one organism benefit while other is unaffected. 

It is a circular reef with an open water at the middle.

A group of built-up exoskeleton of corals that are made up of limestone.  

It is the term given to an organism eat their victim. 

An ecosystem between land and the sea of coastal setting. 

A plant that is rich in organic matter, which serves as marine sources. 

This is parallel with the shore, but it is separated by deeper lagoons. 

It is a small, and isolated reef between fringing and barrier reefs. 

This is the drastic change in the climate due to the increase of greenhouse gases in the atmosphere.

An act of planting trees to replace the denuded ones. 

A ________ object can't move without the presence of force. 

It is a push or a pull. An interaction between two things. 

A force the pull or attract objects toward each other. 

A friction that acts between a moving object and the surface where it is moved. 

A friction happens when two objects slide to each other. 

This is the amount of friction produced when surface is smooth.  

It is a substance that you can put on the surface to reduce the amount of friction.

It is the type of friction that exists between the moving wheels of the vehicle and the road surface.

This friction occurs when the solid surfaces are at rest.

It states that an object at rest will remain at rest unless an outside force acts on it. 

This is the third law of motion.

It is the formula for finding force. 

He formulated the laws of motion.

This law states that with no outside force, an object will not move.

This concept is always related to force.

Gravity is stronger when the object is farther.

Gravitational force has a pushing action.

Gravity is affected by the mass of the objects and their distances.

The object’s weight will remain the same in all planets.

The sun has the strongest gravitational pull in our solar system.

Gravity helps Earth and other planets stay in their orbits as the revolve around the sun.

Ocean tides are caused by the moon’s gravitational pull.

Two objects with different masses will fall at the same time.
