(a) Fungus are non-green plants that grow on dead and decaying matter for their food.
(b) Fungus are also useful as it can cure different type of infections.
(c) Vivek is sincere, curious and knowledge with a keen sense of applying it where necessary.

(b) Autotrophic and Heterotrophic both.
(c) Partial heterotroph.

Yes, the fungi reproduces by spores which are generally present in the air and grow on any article that are left in hot and humid weather for a long time. During rainy season they land on wet and warm things and begin to germinate and grow.

Roots of pulses (leguminous plants) have a symbiotic association with a bacterium called Rhizobium. This bacteria convert gaseous nitrogen of air into water soluble nitrogen compounds and give them to the leguminous plants for their growth. Hence, farmers need not use nitrogenous tertilisers.

(b) Carbohydrates and oxygen.
(c) Liberated-oxygen, Utilised-carbon dioxide.
(d) All plants cannot do photosynthesis, only green plants can do photosynthesis.

Animals like tiger, wolf, lion and leopard are carnivores and do not eat plants. They hunt and eat herbivorous animals like deer, gaur, bison, zebra, giraffe, etc., which are dependent on plants for food.
If there are no plants, herbivorous animals will not survive and ultimately animals like tiger, wolf, lion and leopard will have nothing to eat.

(a) Fungus are saprophytic organisms usually present as spores in atmosphere which can germinate on any substrate in optimal conditions.
(b) Fungus are also useful in that they produce many antibiotics which can cure different types of infections like penicillin.
(c) Harish is sincere, curious and knowledgeable with a keen sense of applying it where necessary.

The process by which green plants can prepare their own food is called photosynthesis. Green plants possess chlorophyll in their leaf and utilises carbon dioxide (from air) water, minerals (from soil, through root) as raw material and sunlight as source of energy and convert light energy into chemical energy. The food thus synthesied is in the form of starch (carbohydrate). The overall reaction for photosynthesis can be given as follows:
