Question 1

Biodegrading

Answer 1

Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi

Question 2

Biomass

Answer 2

refers to the total mass of living plants, animals, fungi, and bacteria in a given area.

Question 3

consumer

Answer 3

Consumer is a category that belongs within the food chain of an ecosystem. It refers predominantly to animals. Consumers are unable to make their own energy, and instead rely on the consumption and digestion of producers or other consumers, or both, to survive.

Question 4

decomposers

Answer 4

A decomposer is an organism that breaks down organic material, such as the remains of dead animals or plants. Decomposers make essential nutrients available to plants and other organisms in the ecosystem.

Question 5

decomposition

Answer 5

Decomposition is the process of breaking down complex organic substances or dead organisms into simpler substances or elements by exposure to heat, light, or chemical or biological activity

Question 6

energy flow

Answer 6

the flow of energy from an ecosystem to an organism and from

Question 7

food chains

Answer 7

Food chains are models that show that flow of energy from plant to animal and from animal to animal. Each step is called a trophic level. the arrows represent ‘giving energy to..’

Question 8

food pyramid

Answer 8

food pyramids show the loss of energy from one trophic level to the next.

Question 9

trophic

Answer 9

a level in a food chain, food web or food pyramid occupied by a groups of organisms that have a similar feeding pattern

Question 10

food webs

Answer 10

A food web is a diagram that shows the interactions between the species in a community that involve the transfer of energy through consumption. It is a combination of food chains that integrate to form a network. It depicts the various methods of feeding, such as herbivory, carnivory, scavenging, and parasitism. the arrows in a food web represent the relationships throughout the web.

Question 11

Photosynthesis

Answer 11

Photosynthesis is a process used by plants, algae, and some bacteria to convert sunlight into energy. The process involves the chemical conversion of carbon dioxide and water into food (sugars) and oxygen. Chlorophyll, a pigment that gives plants their green colour, is often used in the process. The process is essential for almost all life on earth.

Question 12

primary Consumers

Answer 12

A primary consumer is an organism that feeds on primary producers. Organisms of this type make up the second trophic level and are consumed or predated by secondary consumers, tertiary consumers or apex predators. Primary consumers are herbivores, or organisms that only eat plants.

Question 13

Primary Producers

Answer 13

A producer is an autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy) or through chemosynthesis (using chemical energy).

Question 14

secondary consumers

Answer 14

A secondary consumer is an organism that eats primary consumers for energy. Secondary consumers can be carnivores or omnivores. They occupy the second position on the food chain. They are also preyed upon by tertiary consumers, which are organisms that eat secondary consumers.

Question 15

tertiary consumers

Answer 15

A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.
