#1. Which one of the following population interactions is widely used in medical science for the production of antibiotics?

Commensalism

Mutualism

Amensalism

Parasitism

Amensalism (0, –)
Antibiotics are chemicals secreted by one microbial group (eg : Penicillium) which harm other microbes
(eg : Staphylococcus)

It has no effect on Penicillium or the organism which produces it.

#2. Which one of the following plants shows a very close relationship with a species of moth, where none of the two can complete its life cycle without the other?

Hydrilla

Yucca

Viola

Banana

#3. Niche is

all the biological factors in the organism's environment

the physical space where an organism lives

the functional role played by the organism where it lives

the range of temperature that the organism needs to live

#4. Natality refers to

Death rate

Birth rate

Number of individuals entering a habitat

Number of individuals leaving the habitat

Death rate – Mortality

Number of individual entering a habitat is – Immigration

Number of individual leaving the habital – Emigration

#5. Mycorrhizae are the example of

Fungistasis

Amensalism

Antibiosis

Mutualism

Mycorrhizae is a symbiotic association of fungi with roots of higher plants.

#6. Asymptote in a logistic growth curve is obtained when

The value of 'r' approaches zero

K = N

K > N

K < N

population growing in a habitat with limited resources shows logistic growth curve.

#7. Plants which produce characterstic pneumatophores and show vivipary belong to

Mesophytes

Halophytes

Psammophytes

Hydrophytes

Halophytes growing in saline soils show vivipary, which is in-situ seed germination and pneumatophores for gaseous exchange.

#8. Which of the following is correct for r-selected species?

Large number of progeny with small size

Large number of progeny with large size

#9. If '+' sign is assigned to beneficial interaction, '–' sign to detrimental and '0' sign to neutral interaction, then the population interaction represented by '+' '–' refers to

Mutualism

Amensalism

Commensalism

Parasitism

#10. An association of individuals of different species living in the same habitat and having functional interactions is

Population

Ecological niche

Biotic community

Ecosystem

#11. Roots play insignificant role in absorption of water in

Wheat

Sunflower

Pistia

Pea

Pistia – roots are poorly developed as it is free floating hydrophyte.

#12. In which of the following interactions both partners are adversely affected?

Mutualism

Competition

Predation

Parasitism

#13. Most animals are tree dwellers in a

Tropical rain forest

Coniferous forest

Thorn woodland

Temperate deciduous forest

Western Ghat

Meghalaya

Corbett National Park

Keoladeo National Park

#15. Cuscuta is an example of

Ectoparasitism

Brood parasitism

Predation

Endoparasitism

#16. People who have migrated from the planes to an area adjoining Rohtang pass about six months back

Have the usual RBC count but their haemoglobin has very high binding affinity to O₂

Have more RBCs and their haemoglobin has a lower binding affinity of O₂

Are not physically fit to play games like football

Suffer from altitude sickness with symptoms like naussea, fatigue, etc.

#17. Large Woody Vines are more commonly found in:

Alpine forests

Temperate forests

Mangroves

Tropical rainforests

#18. Which one of the following is one of the characteristics of a biological community?

Sex-ratio

Stratification

Natality

Mortality

Stratification is vertical distribution of community.

#19. Geometric representation of age structure is a characteristic of

Ecosystem

Biotic community

Population

Landscape

#20. A good soil is that which

Has very high water holding capacity

Has moderate water holding capacity

Has very low water holding capacity

Allows water to pass through it quickly

#21. Rise in the temperature and air humidity can be observed from

Equator towards polar region

Poles to equator region during latitudinal transition

Plains to mountain top during altitudinal movement

More than one option is correct

#22. A process which maintains constancy of internal body environment of organisms despite varying external environmental conditions is called as

Homeostasis

Heterosis

Antibiosis

#23. Keolado national park is situated at and is famous for .

Gir (Gujarat), Lion

Ranthambhore (Rajasthan), Tiger

Bharatpur (Rajasthan), Siberian cranes

Hazaribag (Jharkhand), Tiger

#24. Altitude sickness which includes nausea, fatigue and heart palpitations occurs due to

High atmospheric pressure at high altitudes

Low atmospheric pressure at high altitude

High mountain height and high temperature

Heavy snowfall at high altitude and low temperature

#25. Altitude sickness is managed by the body by

Decreasing RBC production

Increasing fat oxidation

Decreasing binding capacity of hemoglobin

Decreasing breathing rate

Altitude sickness is managed by the body by decreasing binding capacity of hemoglobin.

#26. Warm blooded animals like mammals from colder climates generally have shorter ear and limbs. This is an explanation of

Jordan’s rule

Allen’s rule

Rensch’s rule

Bergman’s rule

#27. Which is not true for J-shaped growth curve?
