Ecology study guide: one topic on ecosystems, populations or cycles, with worked examples and exercises

Example result

Example for the Standard package

Study guide: solving linear equations, for students aged 13–14

The one rule

An equation is a balance. Whatever you do to one side, you do to the other, and the balance stays level. The goal is to get x alone on one side.

Worked example 3: the unknown on both sides

Solve 5x − 4 = 2x + 11.

  1. Move the x terms to one side: take 2x from both sides. 5x − 2x − 4 = 11, so 3x − 4 = 11.
  2. Move the numbers to the other side: add 4 to both sides. 3x = 15.
  3. Divide both sides by 3. x = 5.
  4. Check: 5 × 5 − 4 = 21 and 2 × 5 + 11 = 21. Both sides match.

Common mistake

In 3(x + 2) = 18, many students write 3x + 2 = 18. The 3 multiplies everything in the brackets: 3x + 6 = 18, so x = 4.

Exercises 7–10

  1. 4x + 3 = x + 18
  2. 2(x − 5) = 14
  3. 7 − x = 3x − 9
  4. 3(2x + 1) = 4x + 15

Answers: 7. x = 5 · 8. x = 12 · 9. x = 4 · 10. x = 6

Files: PDF and Word. The guide is for learning: we do not do homework or tests to be handed in.

Client: a parent whose daughter gets lost when an equation has brackets or the unknown on both sides. Task: a guide at middle school level that starts from the basics and builds up to those two cases. Standard package: up to 8 pages, 6 worked examples, 20 exercises with answers and a summary sheet. Excerpt below.

The client and all details are made up.

About this service

Ecology is about connections: who eats whom, how energy and matter move, why a population grows or crashes. This guide takes one topic at your level, such as food webs, the nitrogen cycle, succession or human impact on ecosystems, and explains it in plain words with the links made visible. Worked examples show how to read a population graph, work out the energy passed between trophic levels or make sense of a simple field survey, and exercises with answers let the learner practise. Tell us the topic, the grade or course, the textbook if any and what is hard. You get PDF and Word files; Premium adds a test and an answer key. The guide explains the science as your course teaches it, without campaigning. It is for learning, so we don't do homework, projects or tests to be handed in.

What is included

  • What you getA PDF and Word guide on one ecology topic: the links and cycles explained in plain words, key terms, worked examples with graphs and data, common mistakes and exercises with answers. From Standard, also a one-page sheet of terms and cycles; in Premium, a self-check test of 20 questions and a separate answer key with short explanations.
  • Connections shownEach link in a web or cycle and what happens if it breaks
  • Cycles step by stepCarbon, nitrogen and water, stage by stage
  • Data examplesPopulation graphs, pyramids and survey tables read with you
  • Exercises with answersFrom labelling a food chain to explaining a change
  • At your levelMiddle school, high school, college or an adult learner

How it works

    TopicYou name the topic, the level and the tricky part
  2. 2
    WritingWe explain the links, add data examples and write the exercises

    StudyYou study with it and ask for changes within your package

What we need from you

The ecology topic (for example, energy pyramids, invasive species or biodiversity), the level or grade, the curriculum and textbook if any, whether the learner must work with graphs or field data, what they already know and find hard, the language and how the guide will be used. You may attach a syllabus or notes as Word or PDF files, up to 3. Please don't send graded projects or exam papers to be solved.

We will ask you:

  • Which ecology topic?
  • For what level?
  • Graphs, data or fieldwork?
  • What is hard, and how will the guide be used?

Questions and answers

Can it cover a local ecosystem?

Yes, if your course studies one, such as a pond or a forest. Tell us which type it is; we use well-known facts about that kind of ecosystem and don't make up local survey data.

Does it cover climate change and pollution?

Yes, as your course presents them: causes, effects and how they are measured, explained plainly and without campaigning.

Will you do my ecology project or homework?

No. We don't do homework, projects, tests or exams to be handed in as the learner's own work; the exercises in the guide are new ones made for practice.

Will it match my curriculum?

We follow the level, curriculum and textbook you name, but programmes and terms differ, so the learner or a teacher should check the guide against the course.
