1. Loss of habitat. 

2. Trees that provide food and shelter to so many species are destroyed due to human intervention.

Over hunting and poaching: 

Large number of animals is hunted for their horns, skin, teeth and many other valuable products.

3. Pollution: 

• Number of animals are affected by pollutions like air pollution and water pollution. 
• In the recent years more number of animals is affected by wastes in the form of plastic. 

4. New habitat: 

• Sometimes animals are taken by people to new habitat where they do not naturally live. 
• Some, of them may extinct and some may survive
• The new ones may also get attacked by the species already living there and cause their extinction.

5. Chemicals: 

• We use pesticides and other chemicals to get rid of damaging insects, pests or weeds. 
• But they can also poison desired plants and animals if we do not use them correctly.

6. Diseases: Diseases due to various unknown reasons may affect the animals and make them extinct.

1. Red Data Book is maintained by the International Union for Conservation of Nature. 

2. It is an international organization working in the field of nature conservation and sustainable use of natural resources.

1. Afforestation helps the wild animals and even humans to have shelter and to find their food source. 

2. Through afforestation we can increase the supply of oxygen. Trees planted can increase the water vapour in the atmosphere to get the rainfall. 

3. By planting trees the amount of carbon dioxide in the atmosphere can be reduced and thus the effects of air pollution, green house gases and global warming can be controlled. 

4. Afforestation enables us to avoid desertification of land. 

5. Barren lands experience strong winds and it causes soil erosion. Top soil is washed away during rainfall. Afforestation helps to grow more trees so that they can hold the top soil along with the nutrients.

6. Creating forests provides us fodder, fruits, firewood and many other resources. 

7. Industries need specific type of trees. Afforestation helps us to grow a particular type of trees.

1. Animal species are endangered mainly because of hunting and poaching. If it is controlled, there can be a significant change in the number of endangered animals. 

2. Controlling pollution can have a positive impact on animals, fish and birds all over the world. 

3. By consuming less pollutants, we can protect the ecosystems. 

4. Animals often mistake plastic for food and hence plastics harm and cause endangerment of many species. Limiting the amount of plastic and recycling it can save the endangered animals. 

5. Recycling things and buying Eco friendly products will preserve the environment resources and hence the animals. 

6. Pesticides and chemicals which cause damage to the environment should be avoided. 

7. Planting native trees will provide food to the animals.

Endemic organisms are confined to a limited geographical area. They cannot adapt or live outside their natural habitat. Any disturbance to their habitat will adversely affect them.

भारत में वायव फोटो का इतिहास पुराना नहीं है। यहाँ सर्वप्रथम 1920 में बड़े पैमाने पर आगरा शहर का वायव फोटो लिया गया था। उसके बाद भारतीय सर्वेक्षण विभाग के वायु सर्वेक्षण द्वारा इरावदी डेल्टा के वनों का वायु सर्वेक्षण किया गया जो 1923.24 में पूरा हुआ था। इसके बाद इस प्रकार के अनेक सर्वेक्षण किए गए। इनका उपयोग उन्नत मानचित्र बनाने में किया गया। वर्तमान में पूरे देश का वाथव फोटो सर्वेक्षण ‘वायव फोटो वायु सर्वेक्षण निदेशालय, नई दिल्ली की देख-रेख में किया जाता है। भारत में तीन उड्डयन एजेन्सियाँ वायु फोटोग्राफ लेने के लिए अधिकृत हैं

⦁    भारतीय वायुसेना

⦁    वायु सर्वेक्षण कम्पनी (कोलकाता) 

⦁    राष्ट्रीय सुदूर संवेदी संस्था (हैदराबाद)

वायव फोटो वायुयान या हैलीकॉप्टर में लगे परिशुद्ध कैमरे के द्वारा लिए जाते हैं। इस तरह से प्राप्त किए गए फोटोग्राफ स्थलाकृतिक मानचित्रों को बनाने तथा लक्ष्यों की व्याख्या करने के लिए उपयोगी होते हैं।

Correct option is (b) personality

Correct option is (b) Mental specifications

फोटोग्राममिति 

यह वायव फोटो द्वारा विश्वसनीय मापन का विज्ञान एवं तकनीक है। फोटोग्राममिति के सिद्धान्त ही वायव फोटो की परिशुद्ध लम्बाई, चौड़ाई एवं ऊँचाई की माप प्रदान करते हैं। यह तकनीक स्थलाकृतिक मानचित्रों को तैयार करने और उनको अद्यतन बनाने में उपयोगी होती है।

प्रतिबिम्ब निर्वचन

प्रतिबिम्ब निर्वचन का अर्थ है फोटोग्राममिति द्वारा प्राप्त चित्र का अध्ययन एवं व्याख्या करना। अत: यह वस्तुओं के स्वरूपों को पहचानने तथा उनके सापेक्षिक महत्त्व से सम्बन्धित निर्णय लेने की प्रक्रिया हैं। इसका उपयोग किसी क्षेत्र के वायव फोटो या सुदूर संवेदन चित्र के द्वारा भौगोलिक जानकारी और उनकी व्याख्या करने के लिए किया जाता है। किसी क्षेत्र की स्थलाकृतियों, वनस्पति, भूमि उपयोग, मिट्टी का प्रकार तथा अन्य भौतिक एवं सांस्कृतिक तत्त्वों का सटीक अध्ययन द्वारा संसाधन, प्रबन्धन एवं नियोजन के लिए प्रतिबिम्ब निर्वचन अत्यन्त उपयोगी होते हैं।

Correct option is (b) perception

Correct answer is  (b) Tetanus

• Some bryophytes are called as liverworts because their gametophyte resembles with lobes of the liver.
• A er a forest fire, when above ground plant parts are killed ferns are o en one first plants to appear? Why?
• On the Forest floor, fern stems live safely tucked below the ground. 
• They survive moderate fires even if all fronds are bumtaway.
• Once rains come and light is available, and when nutrients get released a er the fire, new fronds areproduced easily. 
• Thus ferns are offen the first plants to grow after a fire.

(c) phytaspases

Leaves, flowers and fruits are limited in growth or of determinate or closed form growth

(i) ‘Photo’ means light so, in phototropism light acts as the stimulus. 

(ii) ‘Geo’ means earth or gravity so, in geotropism earth or gravity acts as the stimulus. 

(iii) ‘Chemo’ means chemicals so, in chemotropism chemicals acts as the stimulus.

(d) Pons - consciousness

(b) Contains both sensory and motor fibres

The total period from initial to the final stage of growth is called the grand period of growth. The total growth is plotted against time and ‘S’ shaped sigmoid curve (Grand period curve) is obtained.

Phytochrome: 

(i) It is the pigment which is responsible for flowering. 

(ii) It makes the plant sensitive to light effect. 

(iii) It is known as light absorbing pigment and is responsible for photosensitiveness of plants. 

(iv) It participates in flowering. In long day plants, the light interruption of dark period does not prevent 

(v) If the light is by infra-red, the flowering gets promoted. 

(vi) Phytochrome occurs in two forms-one red absorbing (PR) and the other far red absorbing (P FR). 

(vii) Both the forms are photo-chemically interconvertible. 

(viii) The red absorbing form after absorbing the red light is converted into far red form. 

(ix) They absorbs the infra-red light and is converted back into red absorbing form of pigment. 

(x) Flowering is considered a phytochrome mediated process. 

(xi) Photoperiodism controls flowering in plants. Short-day plants like Xanthium, Chrysanthemum require a relatively short day high period and a continuous dark period of about 14-16 hours for flowering. 

(xii) Dark period is more important to induce flowering than the light period. Flowering can be induced in short day plants by red light treatment followed by far red light treatment.

Absolute growth rate: Increase in total growth of two organs measured and compared per unit time is called absolute growth rate.

Relative growth rate: The growth of the given system per unit time expressed per unit initial parameter is called relative growth rate.

• Lag phase 
• Log phase 
• Decelerating phase 
• Maturation phase

If the length of a plant organ is plotted against time, it shows a linear curve and this growth is called arithmetic growth.

Boron has closely packed metallic structure. It also has small size. So, the melting point of Boron is unexpectedly high.
