Every living thing is part of an incredible web of connections that
keeps our planet alive! In this unit, we will explore how living
organisms interact with each other and with non-living factors
in their environment, how energy moves through food chains,
and how invasive species can disrupt the delicate balance of
ecosystems. We will also investigate how harmful substances
build up in organisms through bioaccumulation and biomagnification.
Finally, we will zoom out to explore Earth’s atmosphere, uncover the differences between weather and climate, travel back through climatic cycles and ice ages, and investigate the changes happening in our atmosphere today. Get ready to discover how everything on Earth is connected—and how our actions can shape the future of our planet!
These are the topics we will study:
-
Biotic and abiotic factors
-
Ecosystems
-
Food Chains
-
Invasive species
-
Bioaccumulation and Biomagnification
-
Climate and weather
-
Climatic cycles and ice ages
-
The Atmosphere
-
Changes in the atmosphere today
Today, I will identify and describe the levels of organization of living things on Earth with curiosity and enthusiasm as I discover how life is connected!
1) After Watching the video about ECOSYSTEM ORGANIZATION define these words in your notebook :
-
Population
-
Community
-
Ecosystem
2) Read this PDF about the way in which living things are organized and define what are biomes? and what is the biosphere?
3) Draw the circles showing the hierarchy of living things. Use this FILE to see the shapes and sizes of the circles.
4) Visit the National Geographic website and answer:
a) Write the 5 major types of biomes
b) What are the further categories in which they can be classified?
c) Choose 1 of these biomes and write at least 3 characteristics
5) Which level of organization is missing in the following image? where should it go?:
Have you ever wondered what makes an ecosystem thrive? Every living thing, from towering trees to tiny insects, depends on both biotic (living) and abiotic (non-living) factors to survive. Sunlight, water, soil, and air shape the world around us, while plants and animals interact to create unique habitats. In this lesson, we’ll explore how these factors work together to support life and why even the smallest changes can have a big impact on an ecosystem. Get ready to dive into the fascinating balance of nature!
Let's solve the following classwork that will help us to learn about these consepts:
1) Write a list of the things you need to be alive.
2) Visit the BYJUS website and define: Biotic factors and Abiotic factors
3) In the following picture of an ecosystem, write the name of 5 biotic and 5 abiotic factors:
4) Do the living things depend on abiotic factors to live? Explain it with your own words or with an example.
5) Visit the CSERC website and define what is a habitat in your notebook, then play the game to match the animals to their habitats. Write 2 examples (2 animals and their habitats)
6) Go to the website, read the text about biotic
and abiotic factos and solve the little quiz at the bottom of the page.
UNIT 3: Planet in balance:
Eco-detectives
Class 1 : Ecological Organization
Class 2: Biotic, abiotic factors and
habitats in an ecosystem
The world is full of incredible diversity, from rainforests full with life to dry deserts where only the toughest plants and animals survive. Every ecosystem—whether on land, in water, or somewhere in between—is shaped by key factors like climate, water availability, and temperature. These factors determine which plants and animals can thrive in a given habitat. Why do camels live in the desert but not in the Arctic? How can some fish survive in saltwater while others need freshwater? In this lesson, we’ll explore the fascinating variety of ecosystems on Earth and discover how living things adapt to their environments. Get ready to travel from the deepest oceans to the highest mountains and uncover the secrets of nature’s balance!
PRESENTATION ABOUT THE ECOSYSTEMS
In the groups assigned by the teacher, investigate and create a short presentation about the ecosystem related to your group number. Make sure it includes:
-
Name of the ecosystem and general description
-
Location (where is this ecosystem found on Earth?)
-
Do we have this ecosystem in colombia?
-
General characteristics (Climate, temperature, precipitation)
-
Common plant and animals found there, (use many pictures/photos)
-
A food chain or food web we can find in the ecosystem
You should use maps to show where the ecosystem
is located, photos and pictures of the animals, habitats
and characteristics, diagrams of food webs and
many other visual aids. The slides should be easy to
read and light in text.
Ecosystems according to the group number:
Group 1: Grassland
Group 2: Moorland (páramo)
Group 3: Tundra
Group 4: Tropical Rainforest
Group 5: Desert
Group 6: Savanna
Group 7: Coral Reef
Group 8: Temperate forest
Class GOAL
I will identify and describe the main characteristics of the world's main ecosystems, including their climate, location, plants, animals, and food chains, while collaborating respectfully with my teammates to create and present an engaging and informative presentation.
