9. organisms
10. herbivores
10. first
12. Heterotrophs
13. second
Explanation:
An ecosystem consists of a community of living organisms
interacting with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.
Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
Answer:
one way of the planet heating up is the fumes of are vehicles it pollutes the ozone layer there for making it slowly go away the ozone layer keeps some of the suns heat out and when its going away its making more heat come through i am not shore if its right but hope it helps and i am also in 11th grade so i know a little
Explanation:
Answer: population, more
Explanation:
Carrying capacity is the size of the population of species that an ecosystem can support in terms of providing essential resources for survival. When the population of the species exceeds the carrying capacity then the population experience decline in population.
An population which produces more number of offspring than the environment can actually support then this will lead to the decline in the population due to the increase in the population beyond the carrying capacity.
