Karena kondisi yang keras, hanya beberapa spesies tumbuhan yang dapat bertahan hidup di tundra. Tanaman ini telah mengembangkan adaptasi khusus untuk mengatasi suhu rendah, musim tanam pendek, dan tanah yang miskin nutrisi. Misalnya, banyak tumbuhan tundra memiliki sistem akar yang dangkal untuk menyerap nutrisi yang tersedia secara terbatas di lapisan tanah atas. Mereka juga memiliki periode pertumbuhan yang cepat untuk memanfaatkan periode singkat cuaca hangat. Tanaman tundra yang umum termasuk lumut, lumut, rumput, dan semak kerdil. Tingkat Trofik dalam Rantai Makanan TundraProdusen utama di tundra berfungsi sebagai sumber makanan bagi konsumen primer, yang merupakan herbivora yang memakan tumbuhan. Hewan tundra yang umum termasuk karibu, rusa kutub, lemming, dan kelinci salju. Hewan-hewan ini telah beradaptasi untuk bertahan hidup di lingkungan yang dingin dengan mengembangkan lapisan lemak yang tebal, bulu yang tebal, dan perilaku seperti hibernasi atau migrasi selama bulan-bulan musim dingin. Konsumen sekunder adalah karnivora yang memakan konsumen primer. Di tundra, konsumen sekunder termasuk serigala, beruang kutub, rubah arktik, dan burung pemangsa. Hewan-hewan ini adalah predator puncak, yang berarti mereka tidak memiliki predator alami. Perbedaan dari Ekosistem LainRantai makanan tundra berbeda dari ekosistem lain dalam beberapa hal penting. Pertama, rantai makanan tundra cenderung lebih pendek daripada rantai makanan di bioma lain. Ini karena jumlah spesies tumbuhan dan hewan yang terbatas yang dapat bertahan hidup di lingkungan yang keras. Akibatnya, ada lebih sedikit tingkat trofik dalam rantai makanan tundra. Kedua, rantai makanan tundra sangat sensitif terhadap perubahan lingkungan. Karena jumlah spesies yang terbatas, hilangnya satu spesies dapat memiliki efek domino pada seluruh ekosistem. Misalnya, penurunan populasi lemming dapat menyebabkan penurunan populasi serigala dan rubah arktik yang bergantung pada lemming sebagai sumber makanan utama. Peran DekomposerDekomposer memainkan peran penting dalam rantai makanan tundra. Organisme ini, termasuk bakteri dan jamur, memecah materi organik mati, seperti tumbuhan dan hewan, menjadi nutrisi yang dapat digunakan kembali oleh produsen utama. Dekomposer sangat penting dalam ekosistem tundra karena mereka membantu mendaur ulang nutrisi yang terbatas dan menjaga kesehatan tanah. Karena suhu rendah dan tanah yang beku secara permanen, proses dekomposisi di tundra jauh lebih lambat daripada di bioma lain.
