Learn about ecological succession and how ecosystems change over time. Understand pioneer species and climax communities!

Which of the following describes the stage of succession likely to have the most species diversity? A newly formed volcanic island An agricultural field that has not been plowed for one year A temperate forest that has never been cleared by logging A field that is regularly mowed 2. During ecological succession, when are pioneer species found? at the very end during early stages during late stages somewhere in the middle stages 3. What occurs during ecological succession? the increase of the number of animal species only gain of climate changes in the environment loss and gain of biodiversity in an ecosystem loss and gain of plant species only 4. What types of organisms are found in a climax community? shrubs and herbaceous plants lichens and mosses poplar and hickory trees beech and sugar maple trees
