There’s too many inaccuracies and omissions to recommend this.
Regarding the two subjects I take the most interest in, this book’s coverage of evolution and ecology is in fact no more detailed, if not worse, than the 2016 middle school study guide for general sciences (which one would expect to have dumbed-down content on any particular subfield of biology):
On Artificial Selection
“ New species can be created by mating only certain individuals in a population if you wanted to create a breed of black dogs from a population of dogs with different-colored coats, only the black dogs would be bred with one another, until alleles for all other fur colors were eliminated from the breed. Humans have used selective breeding to create hundreds of dog breeds, along with many other animals. We've used selective breeding extensively with plants, especially for crops. Selective breeding is like natural selection, except humans are doing the selecting, not nature. ” (Middle School Science)
“ Humans have engineered new species themselves through a process called selective breeding. In this process, two breeds are bred together to produce a new breed with more desirable traits.” A figure of a Labrador retriever and poodle being crossbred is shown. (High School Biology)
On Symbiosis
Sometimes, organisms from different species interact with each other in a way that benefits one or both of them. This is called symbiosis. Symbiosis happens in three different ways: 1. Mutualism: Both species benefit from associating with each other. For example: an oxpecker eats the ticks that attach to zebras. The oxpeckers get food, and the zebras get cleaned. 2. Commensalism: One organism benefits from the relationship while the other remains unaffected. Clown fish, which are resistant to stings from sea anemones, use sea anemones for protection, and the sea anemones are unaffected. 3. Parasitism: One organism, the parasite, feeds off another organism, called the host. Hookworms enter their hosts, such as a dog or human, and feed off nutrients in the host’s small intestine. The hookworms feeds itself by stealing nutrients from the host.” (Middle School Science)
“ [Populations] that help one another often do so in symbiotic relationships, where two or more organisms act in ways that benefit all organisms involved. However, if the environment or climate can’t support normally symbiotic organisms, then will compete with one another for resources, sometimes even preying on one another to increase their chances of survival.” (High School Biology)
Unlike the Middle School Science study guide, High School Biology contains no mention of ecological succession or chemotrophs and no diagrams of food webs or rainforest zonation, and omits the energy pyramid diagram despite having a section labeled “Ecological Pyramid”. Most of the “Plant Adaptations” section is essentially a list of biomes (with little mention of corresponding plant adaptations, incidentally) made redundant by the appropriate section further down in the book.
I’d also add that Passeriformes (the most speciose order of birds) is not among the five selected bird orders listed, a roundworm and a lamprey are represented by the same illustration, a hematophagic “sucker-like mouth with claws or teeth” is implied to be a moderately common feature of the Chondrichthyes (this only applies to the cookiecutter shark, and I suspect someone assumed the jawless fish belonged in this category before being hastily corrected), all modern reptiles (in addition to birds) are implied to be descended from dinosaurs (any 7-year old at this point knows this is patently wrong), a blaze-orange-clad rifleman presumably represents a pre-agricultural hunter-gatherer, “hominids” are implied to include only humans and extinct relatives, and “protists” are still a single kingdom (inexcusable for a 2021 book). Perhaps worst of all, however, are the errors pertaining to photosynthetic eukaryotes.
“…algae…live only in aquatic areas.” Conveniently enough, the book completely ignores that lichens exist)
“…only plants [among organisms] are eukaryotic, multicellular, and have cell walls made of cellulose”. A contradiction on the next page: “Seaweed are protists, eukaryotic, multicellular and have cellulose cell walls. They are not considered plants because they do not have roots, stems, or leaves.” The book neglects to explain that non-vascular plants lack all three of these structures as well.
These (and the lack of detail inherent in this format and the “doodley” art style) seemed to put me off using the book to study the important micro-level topics I was less familiar with (e.g. biomolecules, respiration, photosynthesis). I would definitely caution against using this in place of a standard textbook.
