Biology Unit on the Biosphere: biomes, ecosystems, habitats, feeding relationships, biological interactions

What is the difference between a biome, ecosystem, and habitat?  What is a food web?  What is the energy pyramid? What is symbiosis?  How do different species interact?  What in the world is amensalism or antiobiosis?!  These are some of the things we covered in our latest biology unit!

How We Started Our unit on Biomes: This semester we started with an overview of the main biomes. The kids could come up with the names for all of them, though not the more specialized words (like taiga or chaparral.)  In our biology packet, we have several different notebook pages on the main biomes. The kids did the “fill in the blank” version as we highlighted some of the main features of each biome (there’s also one that is completely filled in, one that just has the biome name and students can write in their own information, and a matching page (which my kids did a couple of weeks later):

Biomes-Worksheets

In the packet, there are full-sized (8 1/2 by 11) photos of each biome.  I chose to print 4 per page which worked well for our needs.  I laminated them and cut them apart.

What are the major biomes?

  • Arctic
  • Alpine Tundra
  • Boreal Forest or Taiga
  • Deciduous Forests
  • Deserts
  • Grasslands
  • Tropical Savannas
  • Chaparral
  • Tropical Rain Forest

Biome-Cards

As we kicked off our unit, I had the kids choose a biome and they each did research and give a 3 to 5 minute speech on what they learned.  They actually loved that!  LD did deserts; DD did hers on the savanna; and ED did rain forests.

We then did an activity on rain forest plants, which I talked about in this post (and which I also explained in the packet).

climate zones-biomesFrom there, we went on to talk about the three main climate zones (and how that relates to the tilt of the Earth on its axis).  And then we started to talk about the abiotic factors of each biome —  ie. the physical, nonliving factors that shape an ecosystem.

Biomes-Abiotic-Factors-WorksheetsThe next week, we went on to talk about the dominant animals and plants in each biome.

Biomes-Dominant-Plants-Animals-Worksheets

The kids spent one day on the anatomy of a cat and dog. You’ll find those sheets in this packet as well:

Animal-Anatomy-PagesFrom there we discussed the difference between habitats and ecosystems. We talked about the difference between producers and consumers (autotrophs and heterotrophs).  And, we talked about the different feeding relationships: herbivores, carnivores, omnivores, detritivores and decomposers.

Biology-Feeding-Relationships

Life BBC DocumentaryOur unit would definitely not have been as amazing without the breathtaking footage and fascinating stories about the animals of our planet!!  We watched the BBC documentary Life (affiliate link) also narrated by David Attenborough as we studied the different biomes, feeding relationships and biological relationships.  This series was the perfect complement to our studies because it really looked in depth at “some of the more colorful strategies the world’s creatures employ to procreate, evade predators, and obtain nourishment. This enthralling BBC series examines “the lengths living beings go to to stay alive.” We highly, highly recommend this documentary:

We spent time talking about food chains, food webs, and the energy pyramid.

Biology-Food-Pyramid-Energy-PyramidIn the last part of this unit, we spent quite a bit of time learning about biological interactions:

  • Amensalism
    • Predation
    • Competition
    • Antibiosis
  • Mutualism
  • Commensalism
  • Parasitism

Biological-Interactions-WorksheetsTo wrap up our unit, we reviewed many of the new terms we had learned about the Biosphere.  :)  The kids (and I!!) definitely learned a lot! :)

Earth’s 4 Major Systems (FREE!): Atmosphere, Geosphere, Hydrosphere, Biosphere (free printable) – When we started our Biosphere unit, we went over the 4 major Earth systems again using these notebook pages. These pages review the 4 major ecosystems and is a good introduction to any unit on earth science, Earth’s atmosphere, biomes, ecosystems & animal habitats, or an ocean unit.

P.S. Our store is getting a bit of a make-over. Hooray!  I can’t tell you how many people have asked me if there was a way to purchase more than one item at a time.  Since I run this blog on my own and always super busy juggling our homeschooling (and homeschool planning), outside activities, and work on the website/business… it has taken a long time to get to this! (Sheepish grin here!)

    Wow sounds a very thorough unit of work. We did all of this last year, it was so interesting and I think I learned as much as the kids!

      It was a fun unit! The kids especially liked the section we did on biological interactions. Many of those terms were new to us, though you know just from experience that some organisms benefit from one another (bee/flower), while some don’t mammals/fleas! Fun unit and I loved picking out all the pictures! :)
      Thanks for leaving a note. I’ll have to go check out and see what you’re up to these days! ~Liesl
