• Competitions are interactions amongst organisms that tries to attain the same resources in an eco system
• Decomposers are living organisms which feed on dead matter

• What is the definition of mutualism 


  A type of ecological interactions where organisms gains benefit from their relationships
• Species are group of organism that can reproduce with one another and make a fertile offspring
• Intraspecific are competition between the same species whereas Interspecific are competition between different species
• Intraspecific- competition between the same species of organisms
• interspecific - competition between different species of organisms
• Keystone - species with significant effect to the food web one the population changes
• Decomposers - living organisms that feed on dead matter. They put back nutrients back in the soil
