When completing this digital assignment, look for these icons that tell you what to do:
Pro Tip: Familiarize yourself with these icons before starting so you can work through the assignment smoothly!
These instructions will help you navigate through the ecosystem activities that follow.
Google Slides has many helpful tools for your ecosystem assignment:
The basic tools let you zoom in/out, insert images, change backgrounds, and select objects. For text, simply click the text box tool to start typing.
The shape tools are super useful for diagrams! You can draw regular shapes, lines, arrows, and connectors by clicking the arrow next to the Line Tool.
Scribble (the bottom option) lets you draw freehand—perfect for creating custom ecosystem illustrations or highlighting relationships between organisms.
Did you know? The curved and elbow connectors are great for creating food web diagrams that show energy flow in ecosystems!
This assignment explores how ecosystems are structured and organized. You'll learn about the different levels that make up ecosystems, from individual organisms to entire communities.
Understanding these levels helps scientists study how living things interact with each other and their environment. Get ready to explore ecosystems from the ground up!
Have you ever mixed up ecosystems and environments? Many students do! Let's clear this up.
An environment is simply WHERE an organism lives—it's the physical place or habitat. Think of it as the address or location.
An ecosystem is much more—it's the complete system of living and nonliving things that interact and exchange energy in that environment. It's like a neighborhood where everyone and everything depends on each other.
Think about it: Your school is an environment, but when you include all the people, plants, animals, and their interactions with things like water, air, and sunlight—that's the ecosystem!
Now it's time to watch a video about ecosystem structure and how ecosystems work. This video will explain the key components and relationships in ecosystems.
Before clicking play, take a quick peek at the questions on the next slide. Knowing what to listen for will help you catch the important details the first time around!
Smart Strategy: You might need to watch the video twice to catch all the answers—this is normal! Pause when you need to take notes.
After watching the ecosystem video, you should be able to answer these key questions:
The difference between ecosystems and habitats: A habitat is just where an animal lives, while an ecosystem includes all living (biotic) and non-living (abiotic) factors in that habitat.
Ecosystem boundaries can be tricky to define because ecosystems often connect to each other—like forests blending into other ecosystem types.
Trophic structure organizes organisms into levels based on energy consumption. This helps track how energy flows through the ecosystem.
Food webs are better than simple food chains because they show multiple interconnected energy pathways, giving a more complete picture of energy flow.
Every ecosystem has two main components that interact with each other:
Abiotic Factors are the non-living parts of an ecosystem. These include things like water, sunlight, soil, temperature, rocks, and air. "Abiotic" literally means "not alive."
Biotic Factors are all the living organisms in an ecosystem. Plants, animals, fungi, bacteria—anything that's alive is biotic. These organisms depend on abiotic factors and other biotic factors to survive.
Remember: The prefix "bio" means life, so "biotic" means related to living things!
The image shows a functioning ecosystem because it contains both living and non-living elements that interact with each other as a whole system.
You can identify an ecosystem by looking for:
These interactions might include animals eating plants, plants using sunlight and soil nutrients, or animals using the environment for shelter.
In this activity, you'll sort components from a farm ecosystem into biotic and abiotic categories.
Biotic factors include all living things on the farm:
Abiotic factors include non-living components:
Drag each component to its correct category to show you understand the difference between living and non-living parts of an ecosystem.
Ecosystems have different levels of organization that help scientists study them:
A population is a group of the SAME species living together in an area. For example, all the rabbits in a forest make up the rabbit population. Each species has its own separate population.
A community includes ALL populations in an area. It's all the different species living and interacting together. The forest community would include all the rabbits, foxes, birds, insects, trees, and other organisms.
Visualization Tip: Think of a population as everyone in your math class (same "species" of student), while the community is your entire school (all different types of students together).

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
