A natural process resulting in the evolution of organisms best adapted to the environment.
A trait that helps an organism survive, thrive and reproduce
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.

Small holes or pores found on leaves that allow carbon dioxide to enter a plant and water vapor and oxygen to leave a plant.
The process by which green plants and other producers convert sunlight into simple sugars. Excess glucose is stored in the plant as starches. Results in the release of oxygen.
The process by which green plants convert stored glucose and starches into energy that can be used for growth. Results in the release of carbon dioxide.
Simple sugar produced by plants during photosynthesis. Is the main energy source for all plants.
A survival strategy for plants. A time when a plant does not grow because it is waiting for the conditions (temperature, moisture, nutrients in soil) necessary for survival to reappear.

A diagram that shows a feeding relationship in which many food chains overlap one another in an ecosystem.
A model used to show the amount of energy available to living things in an ecosystem.
The continuous movement of carbon through the Earth, its atmosphere, and the living things on Earth. Carbon enters the living parts of an ecosystem when plants absorb Carbon Dixoide and turn it into Glucose. Carbon returns to the atmosphere when (1). living things break Glucose down during cellular respiration and (2). living things break down and decay.
The continuous movement of nitrogen through Earth, its atmosphere, and the living things on Earth. Nitrogen enters the living parts of an ecosystem when plants absorb it through their roots.
The continuous movement of water through Earth, its atmosphere, and the living things on Earth. Water is stored in both plants and animals -- and is released as a part of cellular respiration and photosynthesis.
Things in an ecosystem that hold onto carbon for long periods of time. Trees, plants and oceans are all carbon sinks.
The process by which plants pull water to their leaves from their roots.
Thin, hairlike tubes inside of a plant that carry water and nutrients from the roots to the leaves.

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.
