SCIENCE 6 TOPIC 1

LOOK UP THESE WORDS: GIVE A BRIEF DEFINITION TO EACH BIOSPHERE ENVIRONMENT BIOMES HABITATS

LIFE SCIENCE TERMS TO KNOW:

THE BIOSPHERE IS THE PART OF THE EARTH THAT HAS AN ENVIRONMENT WHERE LIFE CAN EXIST

AN ENVIRONMENT CONSISTS OF THE LIGHT, LAND, AIR WATER AND LIVING THINGS FOUND IN AN AREA

THE BIOSPHERE IS BROKEN DOWN INTO BIOMES WHICH ARE VERY LARGE AREAS OF SIMILAR ENVIRONMENTS

THE BIOMES ARE BROKEN DOWN INTO HABITATS WHICH ARE SMALL AREAS SUITABLE FOR CERTAIN LIVING THINGS TO NORMALLY EXIST

YOU SHOULD KNOW EIGHT OF THE MOST COMMON BIOMES

LOOK UP THESE WORDS: WRITE A BRIEF DESCRIPTION TO EACH TUNDRA CONIFEROUS FOREST DECIDUOUS FOREST GRASSLAND DESERT TROPICAL RAIN FOREST

#1: TUNDRA – COLD, PERMAFROST, SHORT GROWING SEASON

#2: CONIFEROUS FOREST – CONE BEARING TREES, POOR SOIL, 2 SEASONS OF SUMMER AND WINTER

#3: DECIDUOUS FOREST – LEAF LOSING TREES, RICH SOIL, ALL 4 SEASONS

#4: GRASSLANDS – DRY SUMMERS, NO TREES OR BUSHES TO SPEAK OF

#5: DESERT – LACK OF RAIN, VERY LITTLE IF ANY VEGETATION

#6: TROPICAL RAINFOREST – WARM AND MOIST ALL YEAR LONG, LUSH GROWTH, RELATIVELY POOR SOIL

#7: WATER – SALTWATER SUCH AS TIDAL BASINS AND OCEAN BOTTOMS

#7: WATER – FRESH WATER SUCH AS MOVING STREAMS AND STILL WATER LAKES

#8: ARID/TEMPERATE – FLATHEAD VALLEY!

THE FOOD CHAIN: THIS DESCRIBES THE FLOW OF ENERGY BETWEEN PRODUCERS AND CONSUMERS

IN A FOOD CHAIN PLANTS ARE PRODUCERS BECAUSE THEY GROW USING NUTRIENTS IN THE SOIL

IN A FOOD CHAIN PRIMARY CONSUMERS (HERBIVORES) LIVE BY EATING THE PLANTS

IN A FOOD CHAIN SECONDARY CONSUMERS LIVE BY EATING THE HERBIVORES

IN A FOOD CHAIN DECOMPOSERS LIKE BACTERIA AND FUNGI RETURN NUTRIENTS TO THE SOIL

A Food Chain Looks Like This… decomposers producers primary consumers herbivores secondary consumers omnivores/carnivores Notice: The arrows point to what eats that organism

THE FOOD WEB IS A MORE COMPLETE PICTURE OF ENERGY TRANSFER THAN THE FOOD CHAIN BECAUSE NOT ALL ANIMALS EAT ONLY ONE KIND OF ANIMAL OR PLANT Notice: The arrows point to what eats that organism

Practice with the Food Chain and the Food Web

A FOOD PYRAMID SHOWS THE RELATIONSHIP BETWEEN A CERTAIN CONSUMER AND THE VARIOUS ORGANISMS NEEDED FOR THAT CONSUMER TO SURVIVE

THE FOOD PYRAMIDS SHOW THREE THINGS: 1. THE TYPE OF CONSUMER 2. THE NUMBER AND TYPE OF ORGANISMS NEEDED FOR THE CONSUMER TO SURVIVE 3. THE AMOUNT OF ENERGY THAT REACHES EACH LEVEL AND IS TRAPPED IN THAT ORGANISM

Here’s another example of a food pyramid A Hawk’s Food Pyramid

And still another example of a food pyramid…
