Food Web and Symbiosis Review

Heterotrophs are also called

'other feeders,' and because they need to consume energy to sustain themselves, they are also known as 'consumers.'

how is the food chain different from the food web?

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

where does a food chain start and end?

A food chain always starts with a producer, an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, an animal that eats a plant or another animal.

examples of parasitism

A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients.

What is the difference between a predator and prey?

A predator is an organism that eats another organism. The prey is the organism which the predator eats. ... The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.

Ecosystem

All the organisms that live in a place, together with their physical environment

3 kinds of consumers

CARNIVORE , HERBIVORE , OMNIVORE

consumer

Consumer gets energy from eating other organisms and from the sun

omnivore

Eat both meat andherbs/plants just like us people.

How is energy transferred between organisms?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.

Niche example

For example, a garden spider is a predator that hunts for prey among plants, while an oak tree grows to dominate a forest canopy, turning sunlight into food. The role that a species plays is called its ecological niche. A niche includes more than what an organism eats or where it lives.

EXAMPLES OF HERBIVORES:

horse,carabao, panda

5 trophic levels and describe whom they eat.

Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers. Level 5: Apex predators that have no predators are at the top of the food chain.

CARNIVORE

Only eat meats and other animals just like leopard, shark,jaguar,tiger and etc.

examples of commensalism

The remora rides attached to sharks and other types of fish. The remora benefits by gaining a measure of protection, and it feeds off of the remains of the meals of the larger fish. The cattle egret is a type of heron that will follow livestock herds.

Heterotrophs examples

You are a heterotroph. Your dog, cat, bird, fish, etc. are all heterotrophs too because you all depend on other organisms as an energy source.

What happens if an organism is removed from an ecosystem

You would also see an effect on the consumers of the frogs which are the snakes. They would lose an organism that they feed on which can cause their numbers to decrease. ... This is why a food web is a more realistic view of how feeding relationships occur in an ecosystem.

food web

a system of interlocking and interdependent food chains.

commensalism

an association between two organisms in which one benefits and the other derives neither benefit nor harm.

heterotrophs

an organism deriving its nutritional requirements from complex organic substances.

autotrophs

an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

decomposers

an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

Decomposers

are organisms that break down dead or decaying organisms. Breaking down dead matter occurs between every trophic level. Because of this, decomposers are not given a sequenced trophic level.

EXAMPLES OF OMNIVORES:

bear, chicken, people

Autotrophs are important

because they are a food source for heterotrophs (consumers).

mutualism example

bee and flower

mutualism

both organisms benefit

EXAMPLES OF CARNIVORES

dinosaur,Pitcher plant,lion

What are trophic levels?

each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.

pioneer species

first species to colonize in barren areas

Examples of decomposers

include bacteria, fungi, some insects, and snails, which means they are not always microscopic. Fungi, such as the Winter Fungus, eat dead tree trunks. Decomposers can break down dead things, but they can also feast on decaying flesh while it's still on a living organism.

Some examples of autotrophs

include plants, algae, and even some bacteria.

symbiosis

interaction between two different organisms living in close physical association, typically to the advantage of both.

Food Chain

is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species

What is a niche?

is a term that is used in ecological biology to define an organism's role in an ecosystem. Not only does a niche include the environment a given organism lives in, it also includes the organism's "job" in that environment.

autotrophs

is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

Ecology

is the study of the interactions of living organisms with one another and their environment

pioneer examples

lichen found on rock, mosses and certain grasses

parasitism

one organism benefits and one organism is affected

herbivore

only eat herbs or plants just like goat,cow ,zebra,elephant and etc.

habitats/ population

place where particular groups of individuals that belong to the same species and live in the same area

what are autotrophs also called?

producers,Autotrophs are also called 'self-feeders,' and they are able to produce energy from sunlight and carbon dioxide and are therefore known as 'producers.'

predation

the preying of one animal on others.

community

when different population that live together in a defined area
