What are the Differences between Biodegradable Wastes and Nonbiodegradable Wastes?

Biodegradable WastesNonbiodegradable Wastes
Origin. They are biological in origin.They are commonly man-made.
Degradability. The wastes are degraded by microorganisms.They are not degraded by microorganisms.
Accumulation. They do not accumulate in nature.They pile up and accumulate in nature.
Biomagnification. The biodegradable wastes do not show biomagnification.The soluble nondegradable wastes enter food chains and undergo biomagnification.
Resource. The wastes can be converted into resource.
Examples. Garbage, livestock wastes, sewage.
Some wastes can be recycled.
Examples. Plastic, polythene, glass, nickel, cadmium, several pesticides.

What are the Differences between Herbivores and Carnivores?

HerbivoresCarnivores
Food. They are animals which feed on plants.Carnivores are animals which feed on other animals.
Canines. The animals do not have well developed canines.Canines are well developed to tear flesh of the prey.
Cellulose. Herbivores harbour microorganisms which degrade cellulose for them.Carnivores do not degrade cellulose.
Ecological Status. Herbivores are primary consumers or second trophic level organisms.
Examples. Deer, Goat, Cow, Mouse.
Carnivores are higher level consumers. They belong to third or still higher trophic level.
Examples. Frog, Fox, Snake (feeding on mouse).

What are the Differences between Carnivore and Omnivore?

CarnivoreOmnivore
Food. It feeds on other animals.It eats both plant and animal food.
Teeth. Canine teeth are well developed. Incisors are less developed.Both canine and incisor teeth are well developed.
Claws. Claws are well developed.Claws are less developed.
Trophic Level. It lies at a fixed trophic level.It operates at two or more trophic levels.
Population. Population of a carnivore depends upon population of its prey.
Examples. Peacock, Lion.
Population of an omnivore is less dependent upon population of its preys.
Examples. Cockroach, Humans, Domesticated Dog.

What are the Differences between Producers and Consumers?

ProducersConsumers
Manufacture of Food. Producers manufacture their own food through the process of photosynthesis.They cannot manufacture their own food. Photosynthesis is absent.
Chlorophyll. They possess chlorophyll.Chlorophyll is absent.
Energy. Producers trap solar energy and change the same into chemical energy.They cannot trap solar energy. Chemical energy is obtained from outside.
Nutrients. They obtain inorganic nutrients from outside.They obtain organic nutrients from outside
Trophic Level. They constitute the first trophic level.Consumers belong to second and higher trophic levels.

What are the Differences between Food Chain and Food Web?

Food ChainFood Web
Units. It consists of a single unit of food relations.It is a complex formed by several units of food relations
Sequence. It is a straight sequence of organisms.It is a network of many linkages among the connected food chains.
Populations. It has a maximum of 4-6 populations of different species.A food web consists of numerous populations of different species.
Food. Only one type of organism is used as food by a particular type of organism.An organism can use two to several types of organisms as food.
Disturbance. A disturbance in food chain is difficult to overcome.A disturbance is overcome after some time.
Endangered Species. It does not help in restoring population of endangered species. Rather it may decline further.A food web helps in increasing population of endangered species.

What are the Differences between Energy Flow and Circulation of Matter?

Energy FlowCirculation of Matter
Addition. Energy is being continuously passed from sun to the ecosystem.No material is added from outside.
Movement. Energy flow is unidirectional. There is no circulation.Materials circulate repeatedly between biotic and abiotic components.
Loss. Energy is dissipated at every level of its transfer and transformation.There is no loss of matter.
Pool. An energy pool does not exist on earth.Nutrient pool occurs in the abiotic environment.
