Question

producers (autotrophs):
consumers (heterotrophs):

• herbivores -
• carnivores -
• omnivores -
• decomposers -

symbiosis:

• mutualism -
• commensalism -
• parasitism -

limiting factors:

• density - dependent
• density - independent:

abiotic vs biotic factors:

• abiotic =
• biotic =

Explanation:

Producers are organisms that make their own food through photosynthesis like plants. Consumers are organisms that eat other organisms. Herbivores eat plants, carnivores eat other animals, omnivores eat both plants and animals. Decomposers break down dead organisms. Symbiosis is a close - long - term relationship between different species. Mutualism is a symbiotic relationship where both species benefit. Commensalism is where one species benefits and the other is neither helped nor harmed. Parasitism is where one species (parasite) benefits at the expense of the other (host). Limiting factors restrict the growth of a population. Density - dependent factors are related to population density (e.g., competition, predation). Density - independent factors affect populations regardless of density (e.g., natural disasters). Abiotic factors are non - living components like temperature, water, soil. Biotic factors are living organisms in an ecosystem.

Answer:

Producers (Autotrophs): Plants, algae, some bacteria
Consumers (Heterotrophs):

• Herbivores: Rabbits, cows, deer
• Carnivores: Lions, wolves, sharks
• Omnivores: Bears, humans, pigs
• Decomposers: Fungi, bacteria, earthworms

Symbiosis: Close long - term species relationship

• Mutualism: Bees and flowers (bees get nectar, flowers get pollinated)
• Commensalism: Barnacles on whales (barnacles get a place to live, whales are unaffected)
• Parasitism: Tapeworms in human intestines (tapeworms benefit, humans are harmed)

Limiting Factors: Factors that control population size

• Density - dependent: Competition for resources, predation
• Density - independent: Earthquakes, floods, wildfires

Abiotic vs Biotic Factors:

• Abiotic: Sunlight, air, temperature
• Biotic: Trees, birds, insects
