Plants and Animals Around Us

Overview

This topic forms a foundational component of Environmental Studies for JTET Paper I, connecting young learners to the living world around them. Questions typically test your understanding of plant and animal classification, their habitats, adaptations, interdependence, and conservation practices—with special emphasis on the biodiversity of Jharkhand.

For the exam, you must know basic plant parts and their functions, animal classification based on food habits and habitats, the concept of ecosystems, and why conservation matters. Expect questions linking local flora and fauna (sal forests, elephants, peacocks) to broader ecological concepts. The pedagogical angle focuses on how teachers can use the immediate environment to make learning meaningful for children.

Mastering this topic requires understanding life processes, ecological relationships, and human responsibility toward nature—themes that recur across EVS questions.

Key Concepts

• **Plant parts and functions**: Roots absorb water and anchor the plant; stems transport water and nutrients; leaves prepare food through photosynthesis; flowers enable reproduction; fruits protect seeds.

• **Types of plants**: Herbs (soft stems, short—tulsi, wheat), shrubs (woody stems, medium height—rose, hibiscus), trees (tall, single woody trunk—sal, mahua, mango), climbers (need support—money plant, grapevine), creepers (spread on ground—pumpkin, watermelon).

• **Animal classification by food habits**: Herbivores eat plants (cow, elephant, deer); carnivores eat other animals (tiger, lion, snake); omnivores eat both (bear, crow, human).

• **Animal classification by habitat**: Terrestrial (land—tiger, elephant), aquatic (water—fish, whale, frog-tadpole), aerial (air—birds, bats), amphibians (both land and water—frog, toad).

• **Adaptation**: Special features that help organisms survive—cactus has thick stems to store water; camel has hump for fat storage; fish have gills for breathing underwater; birds have hollow bones for flight.

• **Food chain and food web**: Energy flows from producers (plants) → primary consumers (herbivores) → secondary consumers (carnivores) → decomposers (bacteria, fungi). Multiple food chains interconnect to form a food web.

• **Interdependence**: Plants provide oxygen, food, and shelter; animals help in pollination (bees, butterflies), seed dispersal (birds, squirrels), and maintain ecological balance.

• **Biodiversity of Jharkhand**: Sal and teak forests dominate; wildlife includes elephants, tigers, leopards, sloth bears, peacocks, and various deer species. Betla National Park and Dalma Wildlife Sanctuary are key protected areas.
