Question 1

1.Biotic

Answer 1

relating to or resulting from living things, especially in their ecological relations

Question 2

2. Abiotic

Answer 2

In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole.

Question 3

3. Population

Answer 3

The current world population is 7.9 billion as of May 2022 according to the most recent United Nations estimates elaborated by Worldometer. The term “World Population” refers to the human population (the total number of humans currently living) of the world.

Question 4

5. Ecosystem

Answer 4

The major types of ecosystems are forests, grasslands, deserts, tundra, freshwater and marine.

Question 5

6. Biosphere

Answer 5

The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere is virtually a closed system with regard to matter, with minimal inputs and outputs.

Question 6

7. Herbivore

Answer 6

A herbivore is an animal that gets its energy from eating plants, and only plants. Omnivores can also eat parts of plants, but generally only the fruits

Question 7

9. Omnivore

Answer 7

An omnivore is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed.

Question 8

11. Food web

Answer 8

A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.

Question 9

12. Energy pyramid

Answer 9

An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.

Question 10

13. Carrying capacity

Answer 10

The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available.

Question 11

16. Mutualism

Answer 11

Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction.

Question 12

17. Commensalism

Answer 12

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.

Question 13

18. Parasitism

Answer 13

Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as “predators that eat prey in units of less than one”.

Question 14

19. Producers

Answer 14

Producers are organisms that make their own food; they are also known as autotrophs. They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food. The most common example of a producer are plants.

Question 15

20. Decomposers

Answer 15

Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.

Question 16

21. Desert

Answer 16

arid land with usually sparse vegetation especially : such land having a very warm climate and receiving less than 25 centimeters (10 inches) of sporadic rainfall annually. 2 : an area of water apparently devoid of life. 3 : a desolate or forbidding area lost in a desert of doubt.

Question 17

22. Tundra

Answer 17

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Question 18

23. Temperate deciduous forest

Answer 18

The temperate deciduous forest is a biome that is always changing. It has four distinct seasons: winter, spring, summer and fall. Winters are cold and summers are warm. Temperate deciduous forests get between 30 and 60 inches of precipitation a year. Precipitation in this biome happens year round.

Question 19

24. Tropical rainforest

Answer 19

Tropical rainforests are mainly located between the latitudes of 23.5°N

Question 20

25. Coniferous forest

Answer 20

coniferous forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas that have long winters and moderate to high annual precipitation. The northern Eurasian coniferous forest is called the taiga or the boreal forest.

Question 21

26. Savanna

Answer 21

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.

Question 22

27. Temperate grassland

Answer 22

Temperate grasslands are areas of open grassy plains that are sparsely populated with trees. Various names of temperate grasslands include pampas, downs, and veldts.
